Functional outcome of neglected perilunate dislocations treated with open reduction and internal fixation

Introduction:

Management of neglected perilunate dislocations is controversial. The various procedures such as open reduction and internal fixation (ORIF), proximal row carpectomy, lunate excision, and wrist arthrodesis have been advocated. The aim of our study was to evaluate the functional outcome of neglected perilunate dislocations managed by ORIF.

Materials and Methods:

Over a period of 10 years (1996 to 2006), 14 patients with neglected perilunate dislocations (undiagnosed or untreated for 6 weeks or more) were managed by ORIF. Six patients had dorsal trans-scaphoid perilunate dislocation, 6 patients had volar lunate dislocation while the remaining two had a dorsal perilunate dislocation The results were evaluated by clinical scoring system of Cooney et al.

Results:

The average followup was 4.1 years (range 2-12 years). All except one of the patients operated earlier than 5 months had good results. Of the four patients operated after 5 months, two had a fair result while two had a poor outcome. Chondral damage to the capitate was noted intraoperatively in both the cases with poor outcomes. The two patients were found to have avascular necrosis (AVN) of the lunate; however, functional outcome was fair in both, and both were able to return to their profession.

Conclusion:

We observed favorable functional results of ORIF in neglected perilunate dislocations up to 5 months after injury. The development of AVN or midcarpal arthritis was not a major disabling factor as long as stability of wrist has been restored. Beyond 5 months, an alternative surgical procedure such as proximal row carpectomy should be contemplated as results of ORIF have not been good uniformly.     

Arthroscopic removal of giant loose bodies in the glenohumeral joint

INTRODUCTION

Loose bodies within the joint because of any cause have the potential for continued growth.

PRESENTATION OF CASE

A 41-year-old man had suffered multiple recurrent dislocations of his left shoulder, accompanied with pain. His anterior apprehension and relocation tests were positive, but no other sign was noted on physical examination. On magnetic resonance imaging and at arthroscopy, two giant loose bodies were seen. They were in the axillary recess and were removed arthroscopically.

DISCUSSION

Most authors recommend surgical removal of the cartilaginous loose bodies to ameliorate the symptoms. Furthermore, the majority of authors recommend a synovectomy to decrease the risk of recurrence. Depending on the size of the chondral loose bodies, removal can be performed via an arthrotomy, arthroscopy with mini-open arthrotomy, or arthroscopy.

CONCLUSION

The source of the loose body should be determined carefully. Other lesions may be associated with the loose body. Arthroscopic treatment is a good option for removing the loose body.     

Conservatively treated acetabular fractures: A retrospective analysis

Background:

There are a few studies reporting the long term outcome of conservatively treated acetabular fractures. The present study aims to evaluate the quality of reduction, and radiological and functional outcome in displaced acetabular fractures treated conservatively.

Materials and Methods:

Sixty-nine patients (55 men and 14 women) with 71 displaced acetabular fractures (mean age 38.6 years) managed conservatively were retrospectively evaluated. There were 11 posterior wall, 5 posterior column, 6 anterior column, 13 transverse, 2 posterior column with posterior wall, 9 transverse with posterior wall, 6 T-shaped, 1 anterior column with posterior hemi-transverse, and 18 both-column fractures. The follow-up radiographs were graded according to the criteria developed by Matta J. Functional outcome was assessed using Harris hip score and Merle d’Aubigne and Postel score at final followup. Average follow-up was 4.34 years (range 2–11 years).

Results:

Patients with congruent reduction (n=45) had good or excellent functional outcome. Radiologic outcome in incongruent reduction (n=26) was good or excellent in 6 and fair or poor in 20 hips. The functional outcome in patients with incongruent reduction was good or excellent in 16 and satisfactory or poor in 10 hips. Good to excellent radiologic and functional outcome was achieved in all patients with posterior wall fractures including four having more than 50% of broken wall. Good to excellent functional outcome was observed in 88.8% of both-column fractures with secondary congruence despite medial subluxation.

Conclusions:

Nonoperative treatment of acetabular fractures can give good radiological and functional outcome in congruent reduction. Posterior wall fractures with a congruous joint without subluxation on computed tomography axial section, posterior column, anterior column, infratectal transverse or T-shaped, and both-column fractures may be managed conservatively. Small osteochondral fragments in the cotyloid fossa or non–weight-bearing part of the hip with a congruous joint do not seem to adversely affect the functional outcome. Displaced transverse fractures with “V” sign may require operative treatment.     

Isolated volar surgical approach for the treatment of perilunate and lunate dislocations

Background:

Volar and/or dorsal surgical approaches are used for surgical treatment of perilunate and lunate dislocations. There are no accepted approaches for treatment in the literature. We evaluated the functional results of isolated volar surgical approach for the treatment of perilunate and lunate dislocation injuries.

Materials and Methods:

9 patients (6 male and 3 female patients average age 34.5 ± 3.6 years) diagnosed with perilunate or lunate dislocations between January 2000 and January 2009 were involved in the study. The reduction was performed through isolated volar surgical approach and K-wire fixation, fracture stabilization with volar ligament repair was performed. Range of wrist joint motion, fracture healing, carpal stability, grip strength, return to work were evaluated and also direct radiographs were taken routinely at each control. The scapholunate interval and the scapholunate angle were evaluated radiographically. Evaluations of the clinical results were done using the DASH, VAS and Modified Mayo Wrist Scores.

Results:

The physical rehabilitation was started at 6^th week, after the K-wires were removed. The average followup was 18.2 months (range 12-28 months). At the final followup, the average flexion extension arc was 105.0 ± 9.6° (74.6% of the other side), the average rotation arc was 138.8 ± 7.8° (81.5% of the other side) and the average radioulnar arc was 56.1 ± 9.9° (86.4% of the other side). The grip strength was 0.55 bar; 83.2% that the uninjured arm. According to the Mayo Modified Wrist score, the functional result was excellent in five patients and good in four and the average DASH score was 22.8. The scapholunate interval was 2.1 mm and scapholunate angle was 51°.

Conclusion:

The clinical and radiological results of the isolated volar surgical approach were satisfactory. The dorsal approach was not needed for reduction of dislocations during operations. Our results showed that an isolated volar approach was adequate.     

Fibular allograft and anterior plating for dislocations/fractures of the cervical spine

Background:

Subaxial cervical spine dislocations are common and often present with neurological deficit. Posterior spinal fusion has been the gold standard in the past. Pain and neck stiffness are often the presenting features and may be due to failure of fixation and extension of fusion mass. Anterior spinal fusion which is relatively atraumatic is thus favored using autogenous grafts and cages with anterior plate fixation. We evaluated fresh frozen fibular allografts and anterior plate fixation for anterior fusion in cervical trauma.

Materials and Methods:

Sixty consecutive patients with single-level dislocations or fracture dislocations of the subaxial cervical spine were recruited in this prospective study following a motor vehicle accident. There were 38 males and 22 females. The mean age at presentation was 34 years (range 19-67 years). The levels involved were C5/6 (n = 36), C4/5 (n = 15), C6/7 (n = 7) and C3/4 (n = 2). There were 38 unifacet dislocations with nine posterior element fractures and 22 were bifacet dislocations. Twenty-two patients had neurological deficit. Co-morbidities included hypertension (n = 6), non-insulin-dependent diabetes mellitus (n = 2) and asthma (n = 1). All patients were initially managed on skull traction. Following reduction further imaging included Computerized Tomography and Magnetic Resonance Imaging. Patients underwent anterior surgery (discectomy, fibular allograft and plating). All patients were immobilized in a Philadelphia collar for eight weeks (range 7-12 weeks). Eight patients were lost to follow-up within a year. Follow-up clinical and radiological examinations were performed six-weekly for three months and subsequently at three-monthly intervals for 12 months. Pain was analyzed using the visual analogue scale (VAS). The mean follow-up was 19 months (range 14-39 months).

Results:

Eight lost to followup, hence 52 patients were considered for final evaluation. The neurological recovery was 1.1 Frankel grades (range 0-3) and two patients with root involvement recovered. At six months bony trabeculae at the graft-vertebrae interface were noted. There were 12 (20 %) cases of graft collapse and one case of angulation which showed no progression. At six months the VAS was 3 (range 0-6). There was no limitation of neck motion at six months in 47 patients.

Conclusion:

Fresh frozen fibular allografts are suitable and cost-effective for anterior fusion in cervical trauma.     

Total hip arthroplasty following failed fixation of proximal hip fractures

Background:

Most proximal femoral fractures are successfully treated with internal fixation but a failed surgery can be very distressing for the patient due to pain and disability. For the treating surgeon it can be a challenge to perform salvage operations. The purpose of this study was to evaluate the short-term functional outcome and complications of total hip arthroplasty (THA) following failed fixation of proximal hip fracture.

Materials and Methods:

In a retrospective study, 21 hips in 20 patients (13 females and seven males) with complications of operated hip fractures as indicated by either established nonunion or fracture collapse with hardware failure were analysed. Mean age of the patients was 62 years (range 38 years to 85 years). Nine patients were treated for femoral neck fracture, 10 for intertrochanteric (I/T) fracture and two for subtrochanteric (S/T) fracture of the hip. Uncemented THA was done in 11 cases, cemented THA in eight hip joints and hybrid THA in two patients.

Results:

The average duration of follow-up was four years (2-13 years). The mean duration of surgery was 125 min and blood loss was 1300 ml. There were three dislocations postoperatively. Two were managed conservatively and one was operated. There was one superficial infection and one deep infection. Only one patient required a walker while four required walking stick for ambulation. The mean Harris Hip score increased from 32 preoperatively to 79 postoperatively at one year interval.

Conclusion:

Total hip arthroplasty is an effective salvage procedure after failed osteosynthesis of hip fractures. Most patients have good pain relief and functional improvements inspite of technical difficulties and high complication rates than primary arthroplasty.     

The use of a dual mobility cup in the management of recurrent dislocations of hip hemiarthroplasty

Background

Dislocation is one of the most frequent causes of failure of hemiarthroplasties of the hip, which is the most common treatment for femoral neck fractures in elderly patients. A revision with conversion to total hip arthroplasty is the gold standard in case of failure of closed reduction: however, the use of standard or modular components shows variable outcomes. The use of a dual mobility cup has been evaluated in patients with unstable implants, given the good outcomes obtained in primary and revision surgery. The aim of this study was to assess the results of revisions by dual mobility cups in unstable hemiarthroplasties.

Materials and methods

Thirty-one patients (mean age 75.4 years) were retrospectively evaluated between 2006 and 2010 after conversion to total hip arthroplasty with dual mobility cups for recurrent dislocations. The mean number of dislocations was 2.6 (range 2–5). The evaluation was performed by the American Society of Anesthesiologists physical function score (ASA) and the Harris hip score, and several radiologic criteria.

Results

The mean follow-up was 3.8 years. No recurrence of dislocation was recorded. The ASA score remained unchanged, and the mean Harris hip score improved from 62.2 before dislocation to 76.0 points postoperatively.

Conclusions

Dual mobility cups may be a useful option in the treatment of a hemiarthroplasty dislocation. No risk of a new revision due to instability after insertion of dual mobility cups resulted in our experience, and this option may be strongly considered in cases of revisions of unstable hemiarthroplasties. Level of evidence IV.

     

Hip arthroplasty in failed intertrochanteric fractures in elderly

Background:

Failed intertrochanteric fractures in elderly patients are surgical challenge with limited options. Hip arthroplasty is a good salvage procedure even though it involves technical issues such as implant removal, bone loss, poor bone quality, trochanteric nonunion and difficulty of surgical exposure.

Materials and Methods:

30 patients of failed intertrochanteric fractures where hip arthroplasty was done between May 2008 and December 2011 were included in study. 13 were males and 17 were females with average age of 67.3 years. There were 2 cemented bipolar arthroplasties, 19 uncemented bipolar, 4 cemented total hip arthroplasty and 5 uncemented total hip arthroplasties. 16 patients had a trochanteric nonunion, which was treated by tension band principles. Total hip was considered where there was acetabular damage due to the penetration of implant.

Results:

The average followup was 20 months (range 6-48 months). Patients were followed up from 6 to 48 months with average followup of 20 months. None of the patients were lost to followup. There was no dislocation. All patients were ambulatory at the final followup.

Conclusion:

A predictable functional outcome can be achieved by hip arthroplasty in elderly patients with failed intertrochanteric fractures. Though technically demanding, properly performed hip arthroplasty can be a good salvage option for this patient group.     

Tuberculosis of hip in children: A retrospective analysis

Background:

Tuberculosis (TB) of hip constitutes nearly 15% of all cases of osteoarticular tuberculosis. We report a retrospective study carried out on 43 children with hip TB.

Materials and Methods:

Forty-three children of TB hip treated between 1971 and 2000 were analysed. Twenty-four children of the early series were treated with streptomycin (S), isoniazid (H) and PAS (Pa) for 18 months (3HPaS, 15 HPa), while 19 children in the later series were treated with isoniazid (H), rifampicin (R) and ethambutol (E) or pyrazinamide (Z) for 12 months [(12 RHE(Z)]. Five out of 18 children with radiologically normal appearing type hip TB were treated with chemotherapy alone and 38 children were subjected to surgery; simple synovectomy alone in 31 hips, joint debridement in six hips, and proximal femoral varisation osteotomy in one. After surgery hips were immobilized in cast for one to three months according to the severity of the disease and patients pain tolerance, and then were mobilized under leg traction in bed gradually till pain subsided completely.

Results:

TB of hip healed with minimum sequelae in all children. In 18 Type one hip TB, normal hip (synovial form) anatomy was maintained, and in 25 patients with advanced lesions some defect in the femoral head and acetabulum was noticed, though painless good hip motion was maintained. Excellent to good results were obtained in 31 children (73.1%), fair in eight (18.6%), and poor in four (9.3%). In four patients with poor results, there was some residual morphological defect in the hip. None developed ankylosis of hip.

Conclusion:

We achieved good outcome with minimum sequelae in this series. The management goal should be aimed not only to heal the disease but also to maintain a painless mobile hip and anatomical cephalocotyloid relationship until maturity, and retard the development of secondary osteoarthritis.     

Dislocation following total hip replacement: the Avon Orthopaedic Centre experience

INTRODUCTION

The aim of this study was to determine the incidence and outcome of dislocation after total hip arthroplasty at our unit.

PATIENTS AND METHODS

In total, 1727 primary total joint arthroplasties and 305 revision total hip arthroplasties were performed between 1993 and 1996 at our unit. We followed up 1567 (91%) of the primary hip arthroplasties and 284 (93%) of the revision hip arthroplasties at 8–11 years after surgery. Patients were traced by postal questionnaire, telephone interview or examination of case notes of the deceased.

RESULTS

The dislocation rates by approach were 23 out of 555 (4.1%) for the posterior approach, 0 out of 120 (0%) for the Omega approach and 30 out of 892 (3.4%) for the modified Hardinge approach. Of dislocations after primary total hip arthroplasty, 58.5% were recurrent. The mean number of dislocations per patient was 2.81. Overall, 8.1% of revision total hip arthroplasties dislocated. 70% of these became recurrent. The mean number of dislocations per patient was 2.87. The vast majority of dislocations occurred within 2 months of surgery.

DISCUSSION

To our knowledge, this is the largest multisurgeon audit of dislocation after total hip arthroplasty published in the UK. The follow-up of 8–11 years is longer than most comparable studies. The results of this study can be used to inform patients as to the risk and outcome of dislocation, as well as to the risk of further dislocation.     

Hip arthroscopy to remove loose bodies after traumatic dislocation

OBJECTIVES: This study was designed to review the incidence of arthroscopically detected intra-articular loose bodies found in patients after traumatic hip dislocation or small acetabular wall fracture which would not otherwise be treated without surgery. DESIGN: Retrospective review. SETTING: Level 1 academic trauma center. PATIENTS: Thirty-six patients who sustained traumatic hip injuries and subsequently had 39 hip arthroscopies between November 1997 and January 2004 were reviewed. INTERVENTION: All patients had standard AP pelvis x-rays and CT scans performed. At our institution, patients with hip dislocations or acetabular wall fractures not otherwise requiring surgery are routinely offered hip arthroscopy to remove loose bodies. The radiographs were reviewed to determine incidence of loose bodies or nonconcentric reduction before hip arthroscopy. Chart review provided incidence of loose bodies found during arthroscopy. MAIN OUTCOME MEASUREMENTS: Comparison was made between radiographic data obtained preoperatively and operative findings. RESULTS: Loose bodies were found in the hips of 33 of 36 patients (92%) who were arthroscoped. Loose bodies were found in 7 of 9 cases (78%) in which standard radiographic studies (AP pelvis x-rays and CT scan) found no loose bodies and a concentric reduction. CONCLUSIONS: Loose bodies are routinely present after closed treatment of hip dislocations or wall fractures not otherwise requiring surgery, even when radiographs are negative. Hip arthroscopy may be indicated for loose body removal when open treatment is not otherwise necessary.     

Conversion of failed hemiarthroplasty to total hip arthroplasty: A short to mid-term follow-up study

Background:

The conversion of hemiarthroplasty (unipolar or bipolar) of the hip to total hip replacement has been reported to be associated with very high rates of intra- and postoperative complications. We present a prospective analysis of the outcome of conversion surgery in patients with failed hemiarthroplasty.

Materials and Methods:

Forty-four cases, 30 women and 14 men, average age 62 years (range 42-75 years) of failed hemiarthroplasty were converted to total hip replacement between January 1998 and December 2004. Groin pain was the main presenting complaint in the majority of the patients (24 out of 44). Six patients had infection and were operated with staged procedure. All acetabular and the majority (86.5%) of femoral components used in our series were uncemented.

Results:

After an average follow-up of 6.4 years (range, two to nine years) Harris hip scores improved from 38 (range 15-62) preoperatively to 86 (range 38 to 100) and 22 (50%) patients were community ambulators without support while 17 (38%) needed minimal support of cane. Fifteen out of 18 (83%) patients who had isolated groin pain preoperatively experienced no pain postoperatively while three patients (17%) reported only partial improvement. Intraoperative and postoperative complications included iatrogenic fracture of the femur in two, femoral perforation in two, partial trochanteric avulsion in two, fracture of the acetabular floor in three hips, and postoperative dislocation in one. None of these complications resulted in a poor long-term outcome. The rate of loosening in our series was 2.3% (one out of 44) after a mean follow-up of 6.4 years with a mean survival of 97.4% at 72 months.

Conclusion:

Conversion of symptomatic hemiarthroplasty to total hip arthroplasty is a safe option that gives good functional results, with marginally higher rates of intra-operative complications. The patients should be warned of the possibility of incomplete relief of groin pain postoperatively.     

Outcome of Gartland type II and type III supracondylar fractures treated by Blount's technique

Background:

According to some orthopedic surgeons, almost all supracondylar humerus fractures should be treated operatively by reduction and pinning. While according to others, closed reduction and immobolization should be used for Gartland type II and some type III fractures. However, the limit of this technique remains unclear. We present 74 patients with displaced extension-type supracondylar fractures treated by closed reduction and immobilization with a collar sling fixed to a cast around the wrist. The purpose of the study is to give a more precise limitation of this technique.

Materials and Methods:

Retrospective data acquisition of 74 patients with a Gartland type II or type III fractures treated by closed reduction and immobilization (Blount''s technique) between January 2004 and December 2007 was done. The mean age was 6.3 years (range, 2–11). The mean time of follow-up was 6.5 months (range, 3–25). All open injuries and complex elbow fracture dislocations or T-condylar fractures were excluded from the study. All patients were evaluated with standardized anteroposterior and true lateral x-rays of the elbow, and Flynn criteria were used for functional assessment.

Results:

Gartland type II fractures had 94% good or excellent final results. Gartland type III fractures had 73% good or excellent final result. The Gartland type III outcome depended on the displacement. The fractures remained stable in 88% for the posterior displacement, and 58% for the posteromedial displacement. These displacements were mild. However, for the posterolaterally displaced fractures, only 36% were stable; 36% had a mild displacement and 27% had a major displacement.

Conclusion:

Pure posterior displacement is more stable than posteromedial displacement which is more stable than posterolaterally displaced fractures. This study suggests that Gartland type II and pure posterior or posteromedial displaced Gartland type III fractures can be treated by closed reduction and immobilization with success.     

Functional outcome of patients undergoing replantation of hand at wrist level-7 year experience

Background:

Replantation is defined as reattachment of amputated limb using neurovascular and musculoskeletal structures in order to obtain recovery of limb. Re-vascularisation involves all the above steps in case of limb injuries that result in a near total amputation.

Aim and Objective:

To study the functional outcome of patients undergoing replantation of hand at wrist level.

Material and Methods:

This is a retrospective study of patients who underwent replantation of total amputation of hand at wrist level within a period of Jan 2003-June 2010. We evaluated post operative functional outcome compared to uninjured hand taking into consideration: 1. The patient''s overall satisfaction with the hand. 2. Recovery of flexor and extensor function of thumb and fingers. 3. Recovery of thumb opposition. 4. Recovery of sensations in the median and ulnar nerve distribution. 5. Ability of surviving hand to perform daily tasks.

Results:

There were total seventeen patients and age range was two years to 55 years. Out of 17 patients,16 were males. All the replantations were successful except for one.

Summary:

The results showed that, although the replanted hands were never functionally as good as the contralateral hand the patients were able to perform most of the daily activities.KEY WORDS: Replantation, wrist amputation, hand amputation     

Evaluation of the Patient-Specific Functional Scale in hand fractures and dislocations

Background

Generic upper extremity disability questionnaires utilize standardized items. The Patient-Specific Functional Scale (PSFS) allows the patient to identify specific self-reported items. This study evaluated the validity of the PSFS to assess outcome in patients with hand fractures or dislocations.

Methods

Adults with hand fractures or dislocations, who completed hand therapy between January 2012 and January 2013, were eligible for inclusion. At the initial and final assessment, each patient was asked to complete the PSFS. Each patient identified three items that were difficult or they were unable to perform, and the degree of difficulty was ranked from 0 to 10 (able to perform at pre-injury level). We excluded patients with an incomplete PSFS. Statistical analyses evaluated the relationships between the PSFS and the independent variables.

Results

There were 63 patients (37 men, 26 women); 21 of the 63 patients underwent surgery for fracture fixation. The mean duration of hand therapy treatment was 2.2 ± 1.4 months. The mean PSFS scores were as follows: initial 3.2 ± 2.2; final 8.1 ± 2.2. There was a significant improvement in PSFS scores from initial to final assessment (p < 0.001) and a moderate correlation (r = 0.3, p = 0.02). There was no statistical difference in PSFS scores between men and women or surgery and no surgery.

Conclusions

In these patients with hand fractures or dislocations, the PSFS indicated significant improvement in function. Using items identified by the patient, the PSFS provides a valuable perspective of outcome and may be used in conjunction with generic disease-specific questionnaire for assessment of the upper extremity.     

Total hip arthroplasty (S-ROM stem) and subtrochanteric osteotomy for Crowe type IV developmental dysplasia of the hip

Background:

Developmental dysplasia of the hip (DDH) in adults with severe pain and disability is best treated by total hip arthroplasty (THA). The purpose of this study was to retrospectively evaluate the outcomes of subtrochanteric shortening osteotomy combined with THA using S-ROM stem for those severe patients with a special focus on the effect of two shapes in the subtrochanteric osteotomy ends: Oblique and transverse.

Materials and Methods:

Twenty one cases with mean age of 43.6 years who met inclusion criteria and were operated between February 2007 and February 2012 were included in the study. Those cases had been divided into two groups (oblique vs. transverse) and all records between the two groups were analyzed.

Results:

The Harris hip score significantly improved from 30.6 (range 18–59) preoperatively to 91.2 (range 87–98) postoperatively by the latest followup. Complications including one deep venous thrombosis, one intraoperative fracture of femur and two dislocations occurred while they were addressed properly afterward. The oblique group showed significant advantages in operative time, union time and additional fixation in comparison with the transverse group.

Conclusions:

In the primary THA for the treatment of irreducible DDH, subtrochanteric oblique osteotomy combined with the freely-rotatable S-ROM stem provided favorable short term outcomes by affording both morphological and functional advantages.     

Functional outcome following proximal humeral interlocking system plating for displaced proximal humeral fractures

Aim:

To assess the functional outcome following internal fixation with the PHILOS (proximal humeral interlocking system) for displaced proximal humeral fractures.

Patients and Methods:

We reviewed 30 consecutive patients treated surgically with the proximal humeral locking plate for a displaced proximal humeral fracture. Functional outcome was determined using the American Shoulder and Elbow Society (ASES) score and Constant Murley score.

Results:

Average age of the patients was 58 years (range, 19-92 years). The average overall ASES score was 66.5. The average overall Constant score was 57.5.

Conclusion:

Our results show that good fracture stability was achieved, and the functional outcome was very good in younger patients and it declined with increasing age. Early mobilization of the shoulder can be achieved without compromising fracture union.     

Evaluation of surgical stabilization of metacarpal and phalangeal fractures of hand

Background:

Optimized functional results are difficult to achieve following hand injuries. This prospective study was undertaken to evaluate the functional outcome after surgical stabilization of metacarpal and phalangeal fractures.

Materials and Methods:

Forty-five fractures of digits of hand in 31 patients were managed by surgical stabilization. Five fractures were fixed with closed reduction and percutaneous Kirschner wire fixation; 10 with external fixator; 26 with open reduction and Kirschner wire fixation; and four with open reduction and plate and screw or screw fixation.

Results:

Final evaluation of the patients was done at the end of three months. It was based on total active range of motion for digital functional assessment as suggested by the American Society for surgery of hand. Overall results were excellent to good in 87%. Better total active range of motion (excellent grade) was observed in metacarpal fractures (47%) versus phalanx fractures (31%); closed fractures (57%) versus open fractures (27%); and single digit involvement (55%) versus multiple digits (29%). Excellent total active range of motion was observed with all four plate and screw/ screw fixation technique (100%) and closed reduction and percutaneous kirschner wire fixation (60%). Twenty-two complications were observed in 10 patients with finger stiffness being the most common.

Conclusion:

Surgical stabilization of metacarpal and phalangeal fractures of hand seems to give good functional outcome. Closed fractures and fractures with single digit involvement have shown a better grade of total active range of motion.
