Constrained total scapula reconstruction after resection of a high-grade sarcoma

Patients with high-grade sarcomas arising from the scapula or periscapular soft tissues traditionally have been treated with either a total scapulectomy or a wide, en bloc, extraarticular scapular resection, termed the Tikhoff-Linberg resection. The major challenge after such resections is to restore shoulder girdle stability while preserving a functional hand and elbow. The current authors describe three patients who had an extraarticular, total scapula resection (modified Tikhoff-Linberg) for a high-grade sarcoma. Each patient had reconstruction with a constrained (rotator cuff-substituting) total scapula prosthesis in an effort to optimally restore the normal muscle force couples of both glenohumeral and scapulothoracic mechanisms. At latest followup, the Musculoskeletal Tumor Society functional score was 24 to 27 of 30 (80%-90%). All patients had a stable, painless shoulder and functional hand and elbow. Forward flexion and abduction ranged from 25 degrees to 40 degrees. Glenohumeral rotation (internal rotation, T6; external rotation -10 degrees) below shoulder level, shoulder extension, and adduction were preserved. Protraction, retraction, elevation, and abduction of the scapula were restored and contributed to shoulder motion and upper extremity stabilization. There were no complications. Total scapula reconstruction with a constrained total scapula prosthesis is a safe and reliable method for reconstructing the shoulder girdle after resection of select high-grade sarcomas. The authors emphasize the clinical indications, prosthetic design, surgical technique, and early functional results.

The reverse shoulder prosthesis for primary and secondary treatment of proximal humeral fractures: a case report

Humeral head fractures are very common among elderly people, often requiring shoulder arthroplasty. One requirement for good function after shoulder arthroplasty is an intact or at least reparable rotator cuff. In patients with multifractured and or osteoporotic tuberosities, refixation leads to the potential risk of redislocation and resorption of the tuberosities or coexisting irreparable rotator cuff tears lead to a high failure rate after implantation of traditional fracture prosthesis, whereas the reverse shoulder arthroplasty may provide better outcome. Here we report of a 79-year-old woman, who fractured both humeral heads at different times. Her right side was treated with a fracture prosthesis, which had to be converted after 2 years to a reverse shoulder prosthesis. Because of coexisting irreversible rotator cuff tear accompanying the second humeral head fracture on her left side, this patient was primarily treated with a reverse shoulder prosthesis. During the most recent follow up, 33 months after reverse shoulder arthroplasty on the left side and 39 months on the right side, the age- and gender-adapted constant score was 88 compared to 59 on the right side. The primary or secondary implantation of the reverse shoulder prosthesis in proximal humeral fractures has to be planned carefully, since long-term results are still lacking and treatment options after failed reverse shoulder arthroplasty are few. Generally, primary implantation of traditional fracture prosthesis is indicated in most cases of humeral head fractures; but in carefully selected cases primary reverse shoulder arthroplasty may be superior and lead to better outcome. Therefore, future research should be conducted to find criteria where the reverse shoulder arthroplasty is indicated as first line treatment of proximal humeral head fractures in elderly patients.

Functional outcome after shoulder arthroplasty for primary osteoarthritis: a multicenter study

Shoulder arthroplasty outcomes have been reported in many case series. Typically, these series have followed either a single prosthesis used to treat a variety of arthritic disorders of the shoulder or experience in a single institution. In contrast, this report of a prospective study summarizes the experience of several surgeons with a single prosthetic design for treatment of primary osteoarthritis of the shoulder. A prospective, multicenter clinical outcome study evaluated 176 shoulders in 160 patients with primary osteoarthritis. This study evaluated a single prosthetic design (Global Shoulder) used by 19 contributing surgeons. Enrollment included 133 total shoulder replacements and 43 humeral head replacements (hemiarthroplasty) in 98 men and 62 women. Neither age nor sex affected whether hemiarthroplasty or total shoulder arthroplasty was performed. Patients with full-thickness cuff tears preferentially had hemiarthroplasty. The decision to perform total shoulder arthroplasty or hemiarthroplasty was based on the surgeon's preference. There were significant improvements (P <.001) in all evaluated and self-assessed outcome parameters from the preoperative baseline for both total shoulder arthroplasty and hemiarthroplasty. The results confirm that prosthetic arthroplasty leads to dramatic improvement in pain, function, and patient satisfaction. Intraoperative complications occurred in 5.4% of cases, and postoperative complications occurred in 7.8%. The most common intraoperative complications were intraoperative fractures, occurring in 9 cases. The most common postoperative complications were glenoid component loosening and humeral head subluxation. Almost all cases of humeral head instability were associated with rotator cuff tears or glenoid component loosening (or both). Seven shoulders underwent 9 additional surgeries during the 5-year study period. Thirteen shoulders in 11 patients were lost as a result of death unrelated to the procedure; 2 shoulders in 1 patient were lost within 3 days/3 months after the bilateral replacements as a result of death from pulmonary embolism. Nine percent of the shoulders (16/176) had full-thickness rotator cuff tears. Eight of the 16 shoulders with full-thickness supraspinatus cuff tears had hemiarthroplasty. All of these tears were isolated to the supraspinatus tendon, and all were repairable. There were no differences in postoperative pain, function, American Shoulder and Elbow Surgeons scores, or range of motion. There were no differences between total shoulder arthroplasty and hemiarthroplasty in those patients with a reparable rotator cuff tear. Total shoulder arthroplasty and hemiarthroplasty for treatment of primary osteoarthritis result in good or excellent pain relief, improvement in function, and patient satisfaction in 95% of cases. Avoiding intraoperative humeral shaft fractures through use of an uncemented, canal-filling prosthetic stem requires careful attention to reaming and component sizing. Postoperative humeral head subluxation is often associated with other factors including rotator cuff tears or glenoid component loosening.     

Die inverse Schulterendoprothese zur Behandlung der Defektarthropathie

OBJECTIVE: Total shoulder replacement for restoration of function and for pain relief of damaged glenohumeral joint accompanied by extensive irreparable cuff defect. INDICATIONS: Any painful shoulder arthropathy with insufficient and irreparable rotator cuff, especially primary defect arthropathy, rheumatoid arthritis with extensive rotator cuff defect, arthropathy after reconstruction of rotator cuff, mutilating rheumatoid arthritis, and crystal-induced arthropathy. Relative: failure of primary shoulder replacement in the presence of an irreparable cuff defect. CONTRAINDICATIONS: Structural or neurogenic lesion of deltoid muscle. Advanced glenoid destruction. Relative: age < 65 years. SURGICAL TECHNIQUE: Anterosuperior or deltopectoral approach. Exposure of glenoid. Resection of humeral head at epi-metaphyseal junction. Complete detachment of anterior, inferior, and posterior capsule from glenoid neck. Preparation of glenoid for cement-free fixation of glenoid base plate (metaglène). Preparation of humeral shaft for implantation of humeral component in 0-10 degrees of retroversion. Screwing of glenosphere to base plate. Insertion of cemented or cement-free modular humeral component. RESULTS: Between 10/1997 and 03/2001, a reverse total shoulder arthroplasty was done in 57 patients (14 men, 43 women; average age 70.1 years). Average follow-up time was 18.2 months. 98% of patients would agree to repeat surgery. Average Constant Score adjusted to age and gender was 94%, 97% for patients not having undergone previous surgery. All patients reported complete or almost complete freedom of pain. On the condition that the deltoid muscle was not damaged during previous surgery, a good improvement of power and function could be obtained. All functional parameters were normal for the patient's age with the exception of a slight limitation of internal rotation (average L5). The power of maintained abduction also corresponded in general to age-specific values. Only grade 1 or 2 inferior glenoid notching was observed but never reaching or surpassing the inferior screw (grade 3 or 4); no glenoid base plate loosening.     

Prosthetic replacement in rotator cuff-deficient shoulders

We reviewed a series of 30 shoulders in 25 patients who had glenohumeral arthritis and rotator cuff deficiency and who underwent prosthetic replacement. Nineteen shoulders underwent humeral head replacement, and 11 shoulders had total shoulder arthroplasty. Meticulous mobilization and reconstruction of the deficiencies in the thin atrophic rotator cuff tissues were attempted in all shoulders. Emphasis was placed on anteroposterior stability, and this was achieved in all shoulders; superior coverage was fully achieved in 15 shoulders and was partially achieved in 11. All shoulders had less pain after surgery, and 93% achieved satisfactory pain relief. Total shoulder arthroplasty and humeral hemiarthroplasty were found to provide similar results with respect to pain relief, functional improvement, and patient satisfaction. Shoulders with hemiarthroplasty gained significantly more active elevation (+52° vs + 2°) after surgery. Cuff repair was easier when a humeral head prosthesis alone was used because less lateralization of the humerus occurred. Also, operative time, anesthesia time, and blood loss were decreased with hemiarthroplasty. Because the lack of glenoid resurfacing did not adversely affect pain relief or function and avoided the potential problem of glenoid loosening, we favor humeral hemiarthroplasty as a treatment for glenohumeral arthritis in the rotator cuff-deficient shoulder.     

A successful reconstruction using a frozen autograft and a pedicled latissimus dorsi flap after a S12345B shoulder girdle resection in a patient with osteosarcoma

We present a case of high-grade osteosarcoma in the proximal humerus in an 8-year-old boy. Massive tumor expansion required a S12345B shoulder girdle resection according to the system of the Musculoskeletal Tumor Society. After wide resection, only a small portion of the distal humerus and none of the rotator cuff muscles would be spared. Because the humeral portion would be too short to support the stem and the soft tissue would be insufficient to cover prosthetic components, we designed a composite reconstruction using a frozen autograft and a pedicled muscle flap. At 2 years postoperatively, our patient exhibited good adaptation and had acquired fine dexterity of the upper limb. To our knowledge, this is the first report regarding a successful composite reconstruction after a S12345B shoulder girdle resection.     

Augmented subscapularis muscle transposition for rotator cuff repair during shoulder arthroplasty in patients with rheumatoid arthritis

The effectiveness of rotator cuff repair by augmented subscapularis transposition via the Leeds-Keio artificial ligament was evaluated in patients with rheumatoid arthritis undergoing total shoulder arthroplasty. The minimum follow-up period was 2 years. Final clinical scores (Hospital for Special Surgery scoring system) and the incidence of radiolucency and upward migration of shoulder components in 20 shoulders with rotator cuff repair by augmented subscapularis transposition were superior to those of 19 shoulders with cuff repair by subscapularis transposition alone and similar to those of 22 shoulders with intact rotator cuffs. In shoulders with augmented subscapularis transposition and intact cuffs, clinical scores continued to improve even after the first postoperative year. Our augmented subscapularis transposition did not increase postoperative complications. We conclude that cuff repair by augmented subscapularis transposition is an acceptable alternative for repairing a supraspinatus or supraspinatus and infraspinatus rotator cuff defect in rheumatoid arthritis patients undergoing total shoulder arthroplasty.     

Allograft reconstruction after resection of malignant tumors of the scapula

The oncologic and functional outcomes of six patients who had scapular allograft reconstruction after scapulectomy for malignant tumors were reviewed. Five patients had Stage IIB and one patient had Stage IB tumors. Total scapulectomy was done in five patients, and partial scapulectomy (glenoid and neck) was done in one patient. Frozen glycerolized scapular allografts were implanted and fixed with plates and screws. The scapular muscles were reattached to the allograft. Tendon reconstruction to replace the excised muscles was done in two patients. The patients were followed up for an average of 3.8 years (range, 2-6 years). Cosmesis, elbow, and hand function were good in all patients. There were no infections, nonunions, or shoulder dislocations. One patient fractured the body of the allograft after a fall. One patient had local recurrence and had scapulectomy 5 years postoperatively. Two patients died 3 and 5 years postoperatively with lung metastases but with functioning grafts. The mean functional result using the Musculoskeletal Tumor Society functional score was 82 (range, 77-87). In this series, scapular allograft reconstruction restored cosmesis, shoulder stability, and function. Preservation or reconstruction of rotator cuff muscles is recommended.     

Subacromial Balloon Spacer for Massive Irreparable Rotator Cuff Tears

Massive irreparable rotator cuff tears (MIRCTs) represent 10% to 40% of cases of rotator cuff abnormality and are challenging to treat. When MIRCTs are unresponsive to nonoperative treatment, surgery may be considered. An arthroscopically inserted biodegradable subacromial balloon spacer (InSpace; Stryker) has grown in popularity in recent years for treatment of patients with MIRCTs. The balloon spacer is made of a copolymer of poly-L-lactide-eco-ε-caprolactone and is expected to fully resorb within 12 months after implantation. Research has suggested the balloon spacer becomes progressively compressed and is slowly replaced with fibrous tissue between the humeral head and the acromion, which may support a prolonged benefit following resorption. Clinical benefits may be achieved through reduced acromiohumeral abutment and subacromial friction during shoulder movement by lowering the humeral head and facilitating humeral gliding. The primary population indicated for use of the implant are patients older than 40 years with persistent shoulder pain and functional disability due to MIRCTs. Contraindications include irreparable subscapularis tears, moderate to severe arthritis, axillary nerve palsy, and known allergy to the implant material. There are not clear indications for use of the implant for treatment of partial-thickness tears or repairable complete rotator cuff tears. Familiari et al. reported that treatment with the balloon spacer was associated with a significant improvement in shoulder function, limited need for revision surgery, and high satisfaction at mean 3-year follow-up. More recently, a prospective multicenter randomized controlled trial was conducted to evaluate the efficacy and safety of the balloon spacer in 93 patients compared to 91 patients undergoing arthroscopic partial repair. Significant and clinically relevant improvements in the American Shoulder and Elbow Surgeons score from baseline were noted in both groups up to the 2-year follow-up.     

关节镜下肩袖肱骨止点内移技术与传统技术治疗巨大肩袖撕裂的疗效比较

目的 :探讨关节镜下肩袖肱骨止点内移技术的可行性,为治疗巨大肩袖撕裂提供一种方案。方法 :自2014年2月至2018年4月行手术治疗巨大肩袖撕裂患者40例,分成2组,研究组20例,男8例,女12例,年龄42～82(57.55±8.90)岁,病程1 h～2年;采用肩袖在肱骨头处止点内移,重建完整肩袖技术治疗巨大肩袖撕裂;对照组20例,男10例,女10例,年龄45～75(57.75±9.10)岁,病程1 h～5年,采用传统清理后部分缝合肩袖或原位高张力下缝合技术治疗巨大肩袖撕裂。采用VAS评分、Constant评分、UCLA评分评价两组临床疗效。结果:40例患者均获随访,时间12～14个月。两组术后VAS评分、Constant评分、UCLA评分与术前比较均明显改善(P0.05);研究组在VAS评分、Constant评分和UCLA评分及疗效明显优于对照组(P0.05)。结论:关节镜下肩袖肱骨止点内移治疗巨大肩袖撕裂在肩关节疼痛缓解,功能改善满意,治疗巨大肩袖撕裂是一种可行的方案。     

肱骨头置换术中肱骨大结节固定及肩袖修复研究进展

目的总结肱骨头置换术中肱骨大结节固定及肩袖修复方式的研究进展。方法广泛查阅近年来国内外肱骨头置换以及肱骨近端骨折治疗相关文献,并进行总结分析。结果肱骨大结节固定及其附着肩袖修复对肱骨头置换术后肩关节功能有明显影响。为促进肱骨大结节愈合,学者就肱骨大结节固定方法及材料进行了研究,但针对不同固定方法及材料缺少随机对照研究及统一的评分量表,同时由于病例数有限,难以进行客观比较。结论肱骨大结节良好复位固定是肱骨头置换术获得较好疗效的重要因素。但就肩关节功能恢复方面,肱骨头置换时一期修复肩袖比大结节复位固定更重要。     

Glenoid loosening in total shoulder arthroplasty. Association with rotator cuff deficiency

Seven cases of total shoulder arthroplasty exhibiting major glenoid radiolucent lines or actual translation of the glenoid component were evaluated to identify factors associated with glenoid loosening. The average time from arthroplasty was 30 months (range, 14-44 months). Six of the patients had severe, incompletely reconstructable rotator cuff tears present at the time of surgery, and one patient developed a cuff tear within 1 year of surgery. The amount of superior migration of the humeral component was closely correlated with the degree of glenoid loosening. With superior displacement of the humeral component, superior tipping of the glenoid component was observed: a "rocking horse" glenoid. For comparison, a contemporary group of 16 consecutive total shoulder arthroplasty patients with intact rotator cuffs were reviewed. The control group had no glenoid loosening an average of 5 years after operation. Upward riding of the prosthetic humeral head in patients with rotator cuff deficiency may contribute to loosening of the glenoid component in total shoulder arthroplasty.     

Antegrade humeral nailing through the rotator cuff interval: a new entry portal

The conventional approach for antegrade intramedullary nailing (AIN) of humerus fractures is associated with persistent pain and compromised shoulder function. Damage to the critical hypovascular zone of the rotator cuff near its insertion on the humerus and/or irritation of the subacromial space by prominent hardware are the factors believed to be responsible for poor shoulder function after AIN of the humerus. This study describes a new entry portal through the rotator interval that minimizes iatrogenic damage to the rotator cuff at its insertion. This approach offers a solution for the disappointing postoperative shoulder function and pain scores associated with conventional antegrade nailing techniques. This study consisted of 33 patients with 34 humeral fractures followed for an average of 34 months. The overall satisfaction rate was more than 90%, according to the ASES (American Shoulder and Elbow Society) score. The mean Constant Score was 84 (SD, 14; range, 17 to 98), and primary bone union was achieved in 32 of the 34 cases.     

Limb-Sparing Resection of the Scapula and Reconstruction with a Constrained Total Scapula Prosthesis: A Case of Multicentric Epithelioid Hemangioendothelioma Involving the Scapula and Surrounding Soft Tissues

Introduction  The scapula is a relatively uncommon site for primary bone sarcomas. Tumors arising from the scapula are often initially contained by the rotator cuff muscles that protect pertinent adjacent muscles as well as the brachial plexus and axillary blood vessels. Limb-sparing resection of a scapula sarcoma is technically complex and requires meticulous dissection and mobilization of the brachial plexus and axillary blood vessels. Several muscles must be capable of being preserved in order to reconstruct the scapula and shoulder girdle with a special customized total scapula replacement. The goal of reconstruction is to restore a stable shoulder girdle to preserve elbow and hand function. Methods and Results  In the procedure demonstrated in this video, limb-sparing scapula resection and reconstruction was performed for a patient with a multicentric epithelioid hemangioendothelioma. The steps of the procedure are detailed along with accommodations made for the multicentric nature of the tumor. To allow for optimal postoperative function and maximum soft tissue coverage, a small constrained scapular prosthesis was utilized. The glenohumeral ligaments were reconstructed with a Gore-Tex aortic graft. Multiple muscle rotation flaps were performed to cover and protect the prosthesis as well as restore shoulder girdle stability. Conclusion  Limb-sparing surgery for scapula sarcomas and anatomic reconstruction with a constrained total scapula prosthesis is a reliable and safe technique for resecting selected sarcomas and reconstructing the shoulder girdle. A stable shoulder girdle can be restored for optimal hand and elbow function. A total scapula prosthetic reconstruction is the authors’ procedure of choice when the deltoid, trapezius, rhomboid, latissimus, and serratus anterior muscles are capable of being preserved. The functional outcome is superior to a forequarter amputation and a flail (nonreconstructed) shoulder in which the extremity is left hanging by soft tissues (nonanatomic method).

Custom total shoulder arthroplasty in inflammatory arthritis. Preliminary results.

Twenty-three patients with inflammatory arthritis and rotator cuff deficiency have undergone 27 custom-fit total shoulder arthroplasties. The design used included a short-stem humeral component and a metal-backed glenoid component with an offset keel. The glenoid component was custom-fit to provide maximum coverage of the glenoid surface. The average age of the patients at the time of surgery was 55 years (range, 20-75 years). All patients had inflammatory arthritis, 16 were on steroids, and all had some degree of rotator cuff involvement ranging from small to complete tears. The average length of follow-up study was 5 years (range, 3-7 years). The average preoperative shoulder score was 36 points (range, 15-50 points) with an average pain score of 7 (of 30) points. Postoperatively, the shoulder score improved to 85 points with a pain score of 28 points. Twenty-one shoulders scored a good to excellent result. Two patients required reoperation, both for recurrent rotator cuff tears, one of which occurred after a fall. Radiographic analysis revealed no incidence of humeral radiolucency and six cases of glenoid radiolucency. Only two of these were progressive and both were associated with irreparable rotator cuff tears. Thus, in the early follow-up, this design of glenoid has decreased the incidence of glenoid radiolucency in this difficult patient population.

Kombinationsverletzungen von Labrum und Rotatorenmanschette

In the case of a shoulder dislocation, standard trauma series (AP / Y) are adequate ¶for radiological diagnosis. Degenerative changes or an excentric position of the humeral head are indicators for additional old or acute pathophysiological problems. If pain and weakness, especially during abduction and external rotation, persist for 2 or ¶3 weeks after repositioning, ultrasonography or MRI is indicated to exclude an accompanying tear of the rotator cuff. The incidence of accompanying rotator cuff tears in cases of anterior or inferior glenohumeral dislocation is in excess of 30% in patients over ¶40 years of age, and may exceed 80% in patients over 60 years of age. Following a first-time traumatic shoulder dislocation prompt operative repair of the acute rotator cuff tear generally leads to satisfactory results. For patients who have suffered a large number of recurrences both a superior and an anterior repair may be indicated, and this leads to better results than a rotator cuff repair alone. In the case of an irreparable rotator cuff defect in combination with a recurrent anterior shoulder dislocation a transfer of the pectoralis major can stabilize the shoulder and restore adequate function.
