Biomechanical comparison of the Locking Compression superior anterior clavicle plate with seven and ten hole reconstruction plates in midshaft clavicle fracture stabilisation

Purpose

The purpose of this study was to characterise the biomechanical properties of the seven hole superior anterior clavicle LCP (locking compression plate) and to compare these with the properties of commonly applied implants used for the stabilisation of clavicular midshaft fractures such as the locking 7- and ten hole reconstruction plate.

Methods

Twenty-four synthetic clavicles were used. A transverse midshaft fracture was induced. The clavicles were fixed with angle stable clavicle LCPs, seven hole and ten hole reconstruction plates (n = 8 each). Twenty cycles of axial compression and torsion were performed for each sample, which was followed by 1,000 cycles of three point bending and ultimately bending to failure. Axial, torsional and cantilever bending stiffness were calculated from the data recorded.

Results

The clavicle LCP showed the highest overall stiffness compared to the seven and ten hole reconstruction plate. Significantly higher stiffness values were found for axial compression and external rotation. In the load-to-failure tests, the ten hole reconstruction plate especially showed early signs of plastic deformation, which might account for early plate insufficiency so frequently observed clinically.

Conclusion

The results indicate that the clavicle LCP, as compared to the reconstruction plates, leads to superior biomechanical stability in the treatment of midshaft clavicle fractures.     

Comparison of the efficacy of a distal clavicular locking plate versus a clavicular hook plate in the treatment of unstable distal clavicle fractures and a systematic literature review

Purpose

The purpose of this study was to retrospectively compare and review the clinical outcomes between the distal clavicular locking plate and clavicular hook plates in the treatment of unstable distal clavicle fractures; moreover, the relevant literature of the two fixation methods was reviewed systematically to identify the non-union, complications, or functional scores, according to the treatment methods and determine which treatment method is better.

Methods

Sixty-six patients with 66 unstable distal clavicle fractures who underwent open reduction and internal fixation with either a distal clavicular locking plate (36 patients) or a clavicular hook plate (30 patients ) were evaluated. The main outcome comparisons included Constant score, rate of non-union, rate of complication, and rate of returning to work three months postoperatively.

Results

No significant difference was found between locking plate and hook plate groups in union rate and Constant score (P > 0.05). However, the results indicated that the distal clavicular locking plate group had a significantly lower rate of complications (P < 0.05) and symptomatic hardware (P < 0.05). In addition, the distal clavicular locking plate facilitated the return to work better than the clavicular hook plate (P < 0.05).

Conclusions

Both distal clavicular locking plate and clavicular hook plate achieved good results in the treatment of unstable distal clavicle fractures; however, internal fixation with a distal clavicular locking plate had greater ability to return to their previous work after surgery in three months and fewer complications than the clavicular hook plate.     

Locking Compression Plate in Musculoskeletal Oncology 'a Friend in Need'

Background

We are presenting our experience in the use of locking compression plate (LCP) after juxta-articular oncological resections in addition to its use in pathologic fracture.

Methods

A retrospective audit of skeletal reconstruction using LCP in 25 cases of long bone tumors was performed from 2008 to 2010. Reconstruction following limb salvage surgery was done in 17 patients and internal fixation of pathological fracture was done in 8 patients. All patients were available for > 12 months of follow-up, and thus assessed for union at the resected ends.

Results

There were 8 males and 17 females in the study. The average age at the time of surgery was 30 years (range, 9 to 66 years). The minimum follow-up was 12 months (range, 12 to 32 months). All patients except three went on to heal successfully. Complications occurred in those three patients: wound infection in one, nonunion in another, and periprosthetic fracture in the other patient. In the remaining patients, union was achieved at an average of 6.5 months after reconstruction in curative resection and 4.75 months after fixation of pathological fractures.

Conclusions

Joint sparing limb salvage surgery was made successfully possible after sekeletal reconstruction with LCP. Its use was also quite effective in pathological fractures with poor bone quality. Use of locking plates for musculoskeletal oncological reconstruction resulted in a good and predictable rate of union.     

Functional outcome after open reduction and internal fixation for symptomatic delayed union and nonunion after fracture clavicle: A series of 31 cases

Background:

Non-union after clavicular fractures can cause significant disability due to pain, impaired function of the shoulder joint and limitations of certain activities, especially in high-demand patients.

Materials and Methods:

31 patients (21 males and 10 females) of symptomatic delayed union or nonunion were treated operatively using plate osteosynthesis with bone grafting where required between January 1994 to September 2005. Out of the 31 patients, 14 cases were of delayed union (no evidence of union > six wks) and 17 cases were of nonunion (no union > three months). Fracture of the lateral one-third and open fractures of the clavicle were not included in the study. Bone grafting was done in 23 patients. The outcome was assessed with the American Academy of Orthopedic Surgeons (AAOS) disabilities of the arm, shoulder and hand (DASH) questionnaire.

Results:

The patients were followed-up for an average of 13 months (range six months to four years). All fractures united with in three months Most of the patients had their DASH scores in the range of 10 to 20, the average being 14.7 in our series. Functionally, this was very much acceptable.

Conclusion:

Open reduction and internal fixation with a plate in conjunction with an autogenous bone graft where required is a successful procedure with good outcome and most of the patients can return to a near normal level of function.     

A Comparison of Ulnar Shortening Osteotomy Alone Versus Combined Arthroscopic Triangular Fibrocartilage Complex Debridement and Ulnar Shortening Osteotomy for Ulnar Impaction Syndrome

Background

This study compared the results of patients treated for ulnar impaction syndrome using an ulnar shortening osteotomy (USO) alone with those treated with combined arthroscopic debridement and USO.

Methods

The results of 27 wrists were reviewed retrospectively. They were divided into three groups: group A (USO alone, 10 cases), group B (combined arthroscopic debridement and USO, 9 cases), and group C (arthroscopic triangular fibrocartilage complex [TFCC] debridement alone, 8 cases). The wrist function was evaluated using the modified Mayo wrist score, disabilities of the arm, shoulder and hand (DASH) score and Chun and Palmer grading system.

Results

The modified Mayo wrist score in groups A, B, and C was 74.5 ± 8.9, 73.9 ± 11.6, and 61.3 ± 10.2, respectively (p < 0.05). The DASH score in groups A, B, and C was 15.6 ± 11.8, 19.3 ± 11.9, and 33.2 ± 8.5, respectively (p < 0.05). The average Chun and Palmer grading score in groups A and B was 85.7 ± 8.9 and 84.7 ± 6.7, respectively. The difference in the Mayo wrist score, DASH score and Chun and Palmer grading score between group A and B was not significant (p > 0.05).

Conclusions

Both USO alone and combined arthroscopic TFCC debridement with USO improved the wrist function and reduced the level of pain in the patients treated for ulnar impaction syndrome. USO alone may be the preferred method of treatment in patients if the torn flap of TFCC is not unstable.     

Treatment of midshaft clavicular delayed and non-unions with anteroinferior locking compression plating

Introduction

Pain and impaired shoulder function are the predominant symptoms of midshaft clavicle non-unions. Obtaining consolidation and improvement of shoulder function is often successfully achieved with osteosynthesis and bone grafting. Most data in the literature pertain to plate osteosynthesis, placing the plate on the subcutaneous superior aspect of the clavicle. Although union rates are generally high, most patients require hardware removal as the plate is prominent under the skin causing pain and cosmetic problems.

Materials and methods

In the current retrospective study, we followed a cohort of 21 consecutive cases (20 patients) with a midshaft clavicular delayed or non-union, treated with anteroinferior plating using a 3.5 mm locking compression plate (LCP) for a mean of 30 months.

Results

We operated on 10 males and 10 females with a mean age of 48.2 years (range 16–65). There was one early plate failure that needed revision. Two patients required hardware removal because of prominence of the plate. All but two patients were satisfied with the final cosmetic result. The average DASH score at follow up was 22.8.

Discussion and conclusions

Anteroinferior plating with a 3.5 mm LCP is a reliable and reproducible treatment of midshaft clavicular delayed and non-union regarding consolidation, function, cosmesis and reduction of second surgery.     

Comparison between open and arthroscopic procedures for lateral clavicle resection

Purpose

Arthroscopic lateral clavicle resection (LCR) is increasingly used, compared to an open approach, but literature does not clearly indicate which approach is preferable. The goal of this study was to compare function and pain between patients who underwent lateral clavicle resection using an open approach and patients treated using an arthroscopic approach.

Methods

Patients who underwent LCR between January 2008 and December 2011 were reviewed. After exclusion, 149 shoulders (143 patients) were eligible for analysis: 41 open and 108 arthroscopic. Disabilities of arm, shoulder and hand (DASH) questionnaire and visual analogue scale (VAS) score were used to assess shoulder function and pain. Complications, operative time, length of hospitalization and resection distance were compared.

Results

At a mean follow-up of three years, patients in the open group had significantly less pain by VAS (mm) (Mdn 10, IQR 23) compared with arthroscopic patients (Mdn 20, IQR 50) (p = 0.036). Operative time (minutes) was significantly less for the open approach (Mdn 24.0, IQR 12) compared with arthroscopic (Mdn 38.0, IQR 15) (p < 0.001). Resection distance (mm) was larger for the open approach (Mdn 7.1, IQR 7.0) compared with the arthroscopic approach (Mdn 3.2, IQR 3.1) (p = 0.006), but was not associated with outcome. No significant differences were found for DASH score, complication rate or length of hospitalization.

Conclusions

Both arthroscopic and open approaches for LCR provide excellent outcome in patients with acromioclavicular pain. Less residual pain was found for the open approach, which has shorter operating time and is likely more cost effective.     

Biplanar Open Wedge High Tibial Osteotomy in the Medial Compartment Osteoarthritis of the Knee Joint: Comparison between the Aescula and TomoFix Plate

Background

The purpose of this study was to compare the results of Aescula and TomoFix plates used for biplanar open wedge high tibial osteotomy in medial osteoarthritis of the knee joint with varus deformity.

Methods

A consecutive series of 50 cases of biplanar open wedge high tibial osteotomy were evaluated retrospectively. Group A contained 25 cases treated by using the Aescula plate, and group T contained 25 cases treated by using the TomoFix plate. Full weight-bearing was permitted at 6 weeks after surgery in group A and at 2 weeks in group T. Clinical evaluations were performed at the final follow-up by using postoperative knee scores and functional scores. Radiographic analysis included postoperative mechanical femur-tibia angle, change in posterior tibial slope angle, and complications related to implants. The mean follow-up periods were 30 months in group A and 26 months in group T.

Results

The knee and functional scores were improved at the final follow-up in both groups (p < 0.05), but no differences were observed between the two groups (p > 0.05). An acceptable correction angle was obtained in 52% of group A and in 84% of group T (p = 0.015). Change in posterior tibial slope angle was larger in group A than in group T (p < 0.001), showing better maintenance of posterior tibial slope in group T. In group A, there were 3 cases of screw loosening and 4 cases of delayed union. In addition, there were residual varus deformities in 7 cases (6 in group A and 1 in group T).

Conclusions

This study shows that firm fixation using a TomoFix plate for open wedge high tibial osteotomy produces better radiologic results and a low complication rate than those of the Aescula spacer plate.     

Internal fixation of fractures of both bones forearm: Comparison of locked compression and limited contact dynamic compression plate

Background:

The locking compression plate (LCP) with combination holes is a newer device in fracture fixation. We undertook a study comparing the LCP with limited contact dynamic compression plate (LC-DCP) in the treatment of diaphyseal fractures of both bones of the forearm.

Materials and Methods:

This is a prospective comparative study, 36 patients (18 in each group) with fractures of both the forearm bones (72 fractures) were treated with one of the two devices. The average age of the patients was 30.5 years (range 16–60 years) with mean followup of 2.1 years (range 1.5–2.8 years). The patients were assessed for fracture union and function and complications and by Disabilities of the Arm, Shoulder and Hand (DASH) score for patient related outcome at the latest followup.

Results:

There was no significant difference in two groups with respect to the range of movements or grip strength. One case had delayed union (LC-DCP group) and another had synostosis (LCP group). Plate removal was done in four cases within the study period with no refracture till the presentation of this report.

Conclusion:

LC plating is an effective treatment option for fractures of both bones of forearm. The present study could not prove its superiority over LC-DCP.     

Locking plate osteosynthesis of clavicle fractures: complication and reoperation rates in one hundred and five consecutive cases

Purpose

Locking plate osteosynthesis has become the preferred method for operative treatment of clavicle fractures. The method offers stable fixation, and would theoretically be associated with a low rate of fracture-related complications and reoperations. However, this remains to be explored in a large cohort, and our purpose was to assess the overall rates of complications and reoperations following locking plate osteosynthesis of mid-shaft clavicle fractures.

Methods

We identified all locking plate osteosynthesis of mid-shaft clavicle fractures operated upon in our department from January 2008 to November 2010 (n = 114). Nine patients did not attend the follow-up at our institution. The study group of 105 fractures (104 patients, 86 males) had a median age of 36 years (14–75 years). Follow-up ranged from 0.5 to 3.5 years. No patients were allowed to load the upper extremity for six weeks. By studying patient files and radiographic material, we assessed complications and reoperations.

Results

Overall, there were 31 cases (30 %) of plate removals for discomfort. There were five cases (5 %) of failure of osteosynthesis: two occurred early after approximately six weeks and three late after ten to 13 months postoperatively.

Conclusion

The overall rate of failure of osteosynthesis is low (5 %). The burden of plate removals in approximately one third of patients should be included in the preoperative information.     

Anatomical versus Non-Anatomical Single Bundle Anterior Cruciate Ligament Reconstruction: A Cadaveric Study of Comparison of Knee Stability

Background

The purpose of this study was to compare the initial stability of anatomical and non-anatomical single bundle anterior cruciate ligament (ACL) reconstruction and to determine which would better restore intact knee kinematics. Our hypothesis was that the initial stability of anatomical single bundle ACL reconstruction would be superior to that of non-anatomical single bundle ACL reconstruction.

Methods

Anterior tibial translation (ATT) and internal rotation of the tibia were measured with a computer navigation system in seven pairs of fresh-frozen cadaveric knees under two testing conditions (manual maximum anterior force, and a manual maximum anterior force combined with an internal rotational force). Tests were performed at 0, 30, 60, and 90 degrees of flexion with the ACL intact, the ACL transected, and after reconstruction of one side of a pair with either anatomical or non-anatomical single bundle ACL reconstruction.

Results

Under manual maximal anterior force, both reconstruction techniques showed no significant difference of ATT when compared to ACL intact knee state at 30° of knee flexion (p > 0.05). Under the combined anterior and internal rotatory force, non-anatomical single-bundle ACL reconstruction showed significant difference of ATT compared to those in ACL intact group (p < 0.05). In contrast, central anatomical single bundle ACL reconstruction showed no significant difference of ATT compared to those in ACL intact group (p > 0.05). Internal rotation of the tibia showed no significant difference in the ACL intact, the ACL transected, non-anatomical reconstructed and anatomical reconstructed knees.

Conclusions

Anatomical single bundle ACL reconstruction restored the initial stability closer to the native ACL under combined anterior and internal rotational forces when compared to non-anatomical ACL single bundle reconstruction.     

The Short-term Follow-up Results of Open Wedge High Tibial Osteotomy with Using an Aescula Open Wedge Plate and an Allogenic Bone Graft: The Minimum 1-Year Follow-up Results

Background

This study examined the results of open wedge high tibial osteotomy with using an Aescula open wedge plate and an allogenic bone graft as a surgical technique for the patients who suffer from osteoarthritis of the knee with a genu varum deformity.

Methods

From March 2007 to August 2007, 33 patients (37 cases) with osteoarthritis of the knee and a genu varum deformity underwent a high tibial osteotomy with using an Aescula open wedge plate and an allogenic bone graft. The patients were followed up for more than 1 year. Before and after surgery, the correction angle of the genu varum was measured by the lower extremity scannogram and the posterior tibial slope, the joint space distance and the time to bone union were evaluated. The functional factors were evaluated using the Knee Society Score.

Results

The average knee score and function score improved from 52.19 ± 11.82 to 92.49 ± 5.10 and 52.84 ± 6.23 to 89.05 ± 5.53, respectively (p < 0.001). According to the lower extremity scannogram, the mean preoperative varus angle was -1.86 ± 2.76°, and the average correction angle at the last follow-up was 10.93 ± 2.50° (p < 0.001). The tibial posterior slope before surgery and at the last follow-up were 8.20 ± 1.80° and 8.04 ± 1.30°, respectively (p = 0.437). The joint space distance increased from 4.05 ± 1.30 mm to 4.83 ± 1.33 mm (p < 0.001). The average time to complete bone union was 12.69 ± 1.5 weeks.

Conclusions

An open wedge high tibial osteotomy using an Aescula open wedge plate and an allogeneic bone graft to treat osteoarthritis of the knee with a genu varum deformity showed good results for the precision of the correction angle, the time to bone union and the functional improvement.     

A prospective study to assess the outcomes of revision anterior cruciate ligament reconstruction

Purpose

Continuously increasing numbers of primary anterior cruciate ligament (ACL) reconstructions invites a parallel increase in graft failures and need for revision ACL reconstruction surgery. High failure rates has previously stigmatised the revision surgery. We performed this study using multiple outcome measures together with clinical examination to offer a full assessment of the outcomes of this procedure.

Methods

Twenty patients, with mean age of 29.4 years (17–50 years), were included in this study prior to their revision ACL reconstruction surgery. All patients were followed prospectively collecting the Knee injury and Osteoarthritis Outcome (KOOS), International Knee Documentation Committee (IKDC) and Tegner-Lysholm scores pre- and post-operatively together with clinical assessment of the antero-posterior knee laxity.

Results

After a mean follow up interval of 30 months (16–60 months) significant post-operative improvement of IKDC, Tegner-Lysholm scores and knee antero-posterior laxity together with the Symptoms, Activities of Daily Living (ADL) and Quality of Life (QOL) components of the KOOS score was noticed (P < 0.05). However, there was no similar improvement in pain and sports components of the KOOS score (P > 0.05). There was no difference in the outcomes of different graft types.

Conclusion

Good outcomes of revision ACL reconstruction surgery are achievable. The use of different graft types did not affect the outcome of the procedure. Most of the patients opted to less aggressive sports participation after the revision procedure.     

Carpometacarpal Joint Fracture Dislocation of Second to Fifth Finger

Background

Carpometacarpal joint fracture dislocation of the second to fifth finger is a rare hand injury associated with high energy trauma. Due to severe swelling and overlapping of bones on the radiograph of wrist-hand, dislocations are missed. We reported a series of six patients with rare carpometacarpal joint fracture dislocation treated with open reduction.

Methods

We retrospectively studied six cases of carpometacarpal joint fracture dislocation. All patients were treated with open reduction and internal fixation with Kirschner wire. Functional assessment was done with Quick Disabilities of the Arm, Shoulder and Hand score (Quick DASH score) at regular intervals.

Results

Average Quick DASH score was improved from 75.76 to 1.9 from 6 weeks to 18 months of duration. Of the six patients, three patients had a Quick DASH score of 0 at the end of 18 months.

Conclusions

Careful hand examination and radiographic assessment is necessary to avoid missed diagnosis of carpometacarpal joint fracture dislocation. Early open reduction and internal fixation lead to excellent recovery of hand function.     

Effects of reduction in shoulder pain on quality of life and community activities among people living long-term with SCI paraplegia: a randomized control trial

Objective/background

People with spinal cord injury (SCI) paraplegia can develop shoulder problems over time, which may also cause pain. Shoulder pain may complicate or interfere with a person''s daily activities, social events, and their overall quality of life (QOL). The purpose of this study was to examine changes in social interaction and QOL after an exercise treatment for shoulder pain in people with SCI paraplegia.

Design

Fifty-eight participants with SCI paraplegia who were also experiencing shoulder pain were selected and randomized to either an exercise treatment or a control group. Participants in the treatment group participated in a 12-week, at-home, exercise and movement optimization program designed to strengthen shoulder muscles and modify movements related to upper extremity weight bearing.

Methods

Participants filled out self-report measures at baseline, 12 weeks later at the end of treatment, and at a 4-week follow-up.

Outcome measures

The Wheelchair User''s Shoulder Pain Index (WUSPI), the Social Interaction Inventory (SII), and the Subjective Quality of Life Scale.

Results

From the baseline to the end of treatment, repeated-measures analysis of variance revealed a significant interaction between WUSPI and SII scores, P < 0.001, and between WUSPI and QOL scores, P < 0.001.

Conclusion

Reductions in shoulder pain were related to significant increases in social participation and improvements in QOL. However, increases in social participation did not significantly affect improvements in QOL.     

Hand function in female patients with hand osteoarthritis: relation with radiological progression

Objective

We aimed to investigate the effect of hand osteoarthritis (HOA) on hand strength, dexterity, and upper extremity functional scores, as well as to determine the relation of radiological severity of HOA with these parameters.

Methods

Sixty patients and 40 controls were enrolled in the study. The presence of hand pain, nodes, and tenderness in hand joints was determined. Grip and pinch strengths were measured by Jamar dynamometer and pinch meter, dexterity was assessed by Purdue pegboard test, and upper extremity function was determined by disabilities of arm, shoulder and hand (DASH) test. Hand radiographs were evaluated according to the Kallman grading scale.

Results

The mean age of the patients and control subjects were 58.9 ± 4.8 and 56.6 ± 5.8 years, respectively. The level of hand pain and tenderness, and the number of nodes were significantly higher in the patient group than in control subjects. The mean grip and pinch strengths were lower in the patient group,: however, the difference was significant only in left lateral and left three chuck pinch. In hand dexterity, all scores except Purdue 1 were significantly lower in the patient group. In the functional evaluation DASH outcome, questionnaire scores of the patient and control groups were 48.3 ± 26.3 and 39.5 ± 23.5, respectively (p > 0.05). In the patient group, Kallman scores indicating radiological severity were found to be correlated with age, DASH scores, grip and pinch strengths, and Purdue scores (except Purdue assembly). Pain by visual analog scale was significantly higher in the patient group and correlated significantly with DASH scores.

Conclusion

In patients with HOA, using standardized tests for evaluations may not be adequate. The determination of grip–pinch strength, dexterity and functional disability will lead to a clearer definition of the needs of the patients and will likely increase the gains from the rehabilitation programs.     

Plate versus titanium elastic nail in treatment of displaced midshaft clavicle fractures: A comparative study

Background:

With changing trends in treatment of displaced midshaft clavicle fractures (DMCF), plating remains the standard procedure for fixation. An attracting alternative method of fixation is the titanium elastic nailing (TEN). However, prospective randomized studies comparing the two methods of fixation are lacking. We assessed the effectiveness of minimally invasive antegrade TEN and plating technique for the treatment of DMCF.

Materials and Methods:

80 unilateral displaced midclavicular fractures operated between October 2010 and May 2013 were included in study. This prospective comparative study was approved by the local ethical committee. Followups were at 2^nd and 6^th weeks and subsequently at 3, 6, 12, 18 and 24 months postoperatively. Primary outcome was measured by the Constant score, union rate and difference in clavicular length after fracture union. Secondary outcome was measured by operative time, intraoperative blood loss, wound size, cosmetic results and complications.

Results:

During analysis, we had 37 patients in the plate group and 34 patients in the TEN group. There was no significant difference in Constant scores between the two groups. However, faster fracture union, lesser operative time, lesser blood loss, easier implant removal and fewer complications were noted in the TEN group.

Conclusion:

The use of minimally invasive antegrade TEN for fixation of displaced midshaft clavicle fractures is recommended in view of faster fracture union, lesser morbidity, better cosmetic results, easier implant removal and fewer complications; although for comminuted fractures plating remains the procedure of choice.     

Association between individual DASH tasks and restricted wrist flexion and extension after volar plate fixation of a fracture of the distal radius

Background

Symptoms and psychosocial factors are suggested to account for more of the variation in disability than physical impairment, but perhaps less so at the level of specific tasks. This study assessed the influence of impaired wrist motion on specific tasks on the Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire.

Methods

Sixty-three patients with an operatively treated fracture of the distal radius completed the Pain Catastrophizing Scale (PCS), Pain Anxiety Symptoms Scale, and Center for Epidemiologic Studies Depression Scale (CES-D) just before surgery and the DASH questionnaire 3 months after surgery. Nine questions on the DASH were selected as potentially sensitive to changes in wrist motion and evaluated in bivariate and multivariable analyses.

Results

In multivariable models of factors associated with specific tasks, only “Open a tight or new jar” was affected by wrist flexion and PCS accounting for 33 % of the variation. Motion, pain, and PCS were significant predictors of the DASH score. Among the eight tasks not related to wrist motion, 33 % of the variation in disability with writing was accounted for by PCS and limb dominance; 20 % of disability preparing a meal by pain, CES-D, and PCS; 14 % of disability with making a bed by pain and CES-D; and 23 % of changing a light bulb overhead by age, pain, and fracture type.

Conclusions

After volar plate fixation of a fracture of the distal radius, upper extremity disability based on select items from the DASH questionnaire correlated minimally with impairment of wrist motion, even at the level of specific tasks.

Functional outcome of collagenase injections compared with fasciectomy in treatment of Dupuytren’s contracture

Background

This study was designed to provide comparative information on the safety and efficacy of injection with collagenase clostridium histolyticum (CCH) and fasciectomy for patients with Dupuytren’s contracture (DC).

Methods

A single-center, retrospective, observational, longitudinal chart review was conducted of 25 patients treated with CCH injections and 21 patients undergoing fasciectomy. Patients were assessed at 1 week, monthly for 3 months and then yearly for a minimum of 2 years after treatment for changes in contracture and range of motion, time to return to work/normal activities, patient satisfaction, and Disabilities of Arm, Shoulder and Hand (DASH) score.

Results

Post-procedure follow-up averaged 32 months for the injection group compared with 39 months for fasciectomy group. For the CCH group, the mean postinjection contracture was 3.6° for the metacarpophalangeal and 17.5° for the proximal interphalangeal joints compared with 3.7° and 8.1° in the fasciectomy group, respectively. Patients treated with injections returned to normal activities after a mean of 1.9 days compared with 37.4 days for fasciectomy patients (p < 0.0001). DASH scores for 13 CCH and 15 fasciectomy patients were obtained. The mean DASH score was significantly lower in the injection group in the first 3 months (p < 0.01). At the 2-year follow-up visit, patients were satisfied with their outcomes following either treatment (92 % and 96 % of CCH and fasciectomy patients, respectively).

Conclusion

CCH injections are safe and effective and may be a viable alternative to fasciectomy for treating DC. It also allows earlier return to work and daily activities.
