The purpose of this study is to report the outcome of arthroscopically assisted lower trapezius transfer to reconstruct irreparable posterior-superior rotator cuff tear.
Forty-one consecutive ...patients with irreparable posterior-superior rotator cuff tears who underwent an arthroscopically assisted transfer of the lower trapezius transfer were included in this study. The patients’ average age was 52 years (range 37-71), and average follow-up was 14 months (range 6-19 months). Nineteen patients had true pseudoparalysis preoperatively, whereas 66% had a prior failed rotator cuff repair. Outcome measures included visual analog scale (VAS) pain score, range of motion, Subjective Shoulder Value (SSV), and Disabilities of the Arm, Shoulder, and Hand (DASH) score.
Thirty-seven (90%) patients had significant improvement of all outcome scores: VAS, SSV, and DASH. The presence of a subscapularis tear did not affect the outcome. However, 3 patients who had preoperative rotator cuff arthropathy changes of the shoulder had persistent pain and limited range of motion of the shoulder after surgery, and 2 of them underwent reverse shoulder arthroplasty. Two additional patients had a traumatic rupture of the transfer as a result of fall (at 5 and 8 months postop). One underwent revision arthroscopic repair and did well after surgery, and the other had good pain relief but recurrent weakness and limited range of motion, and elected not to have a revision surgery.
Arthroscopic-assisted lower trapezius transfer may lead to a good outcome in patients with massive irreparable posterior-superior rotator cuff tears, including patients with pseudoparalysis. The presence of an associated reparable subscapularis tear did not affect the outcome.
Background Management of massive irreparable posterior-superior rotator cuff tear can be very challenging. This study reports the outcome of the lower trapezius transfer to reconstruct massive ...irreparable posterior-superior rotator cuff tear. Methods Included were 33 patients with an average age of 53 years (range, 31-66 years). All patients had symptomatic massive irreparable rotator cuff tear that failed conservative or prior surgical treatment and underwent reconstruction with lower trapezius transfer prolonged by Achilles tendon allograft. The tear was considered irreparable based on the magnetic resonance imaging finding of ≥2 full-thickness rotator cuff tears associated with shortening and retraction of the tendon to the level of the glenoid and a high grade of fatty infiltration of the muscles. This was confirmed at the time of the surgery. Results At an average follow-up of 47 months, 32 patients had significant improvement in pain, subjective shoulder value, and Disabilities of the Arm, Shoulder and Hand score and shoulder range of motion, including flexion, 120°; abduction, 90°; and external rotation 50°. One patient, with a body mass index of 36 kg/m2 , required débridement for an infection and then later underwent shoulder fusion. Patients with >60° of preoperative flexion had more significant gains in their range of motion. Shoulder external rotation improved in all patients regardless of the extent of the preoperative loss of motion. Conclusions Transfer of the lower trapezius prolonged with Achilles tendon allograft to reconstruct massive irreparable posterior-superior rotator cuff tear may lead to good outcome in most patients, specifically for those who have preoperative flexion of >60°.
There is a paucity of information on latissimus dorsi transfer (LDT) for subscapularis insufficiency. The purpose of this study is to report the outcome of LDT to reconstruct an irreparable ...subscapularis tear.
Excluding patients with prior failed Latarjet procedures, we examined 56 consecutive patients who underwent open (n = 14) or arthroscopic (n = 42) LDT. The average age was 53 years (range, 23-79), and 46 patients had a prior surgery. Outcome measures included visual analog scale score for pain, range of motion (ROM), subjective shoulder value (SSV), and Constant shoulder score (CSS).
At a mean 13-month follow-up (7-51 months), patients had significant improvements in their pain, ROM, SSV, and CSS when compared to preoperatively. At final follow-up, 26% of patients continued to have proximal migration, and 11% of patients had anterior subluxation. The patients with frank anterior escape had a higher likelihood of having proximal migration and anterior subluxation, but this was not statistically significant. Stages of arthritis did not progress. Revision surgeries included 2 patients who revised to a reverse shoulder arthroplasty for rupture of the tendon transfer. Furthermore, 3 patients had LDT ruptures but did not elect to undergo further surgery.
LDT for irreparable subscapularis tears has the potential to lead to significant clinical improvements. Most patients improve in many of the signs of subscapularis insufficiency, including anterior and/or proximal subluxation, clinical examination maneuvers, and shoulder function. Overall, this transfer represents a reasonable option for this difficult pathology.
Purpose To examine the long-term outcome of patients aged less than 45 years who underwent either proximal row carpectomy (PRC) or 4-corner arthrodesis (4CA) for wrist arthritis. Methods We reviewed ...a retrospective cohort of 89 patients aged less than 45 years who underwent either 4CA (n = 51) or PRC (n = 38) for wrist arthritis. Mean follow-up was 11 years in the 4CA group and 18 years in the PRC group. Results Overall, there were no differences between groups in the need for revision surgery. Complications included 6 nonunions in the 4CA group (12%), 1 infection in each group, and 11 patients who experienced radiocarpal impingement (8 4CA and 3 PRC). There was no difference in the number of patients reporting moderate or severe pain between the PRC and 4CA groups. Mean flexion-extension arc was 54° after 4CA, compared with 73° after PRC. Patients who underwent 4CA had slightly improved grip strength (65% of the opposite side) compared with those who had PRC (54%). Mean postoperative Disabilities of the Arm, Shoulder, and Hand questionnaire scores were 32 versus 19 (PRC vs 4CA) and patient-rated wrist evaluation scores were 27 versus 28 (PRC vs 4CA). Comparing radiographic arthritis, the 10-year outcome, free of moderate/severe arthritis for the PRC and 4CA groups, was 70% and 71%, respectively. Conclusions Both PRC and 4CA represent a good surgical option for young patients with wrist arthritis, with similar complication rates, postoperative pain levels, wrist function, and long-term outcomes free of arthrodesis. Proximal row carpectomy has improved motion and fewer complications. Type of study/level of evidence Therapeutic IV.

Recurrent anterior shoulder instability is associated with glenohumeral bone loss. Glenoid deficiency compromises the concavity-compression mechanism. Medial Hill-Sachs lesions can result in an ...off-track humeral position. Anterior glenoid reconstruction or augmentation prevents recurrence by addressing the pathomechanics. In Bristow and Latarjet procedures, the coracoid process is harvested for conjoint tendon transfer, capsular reinforcement, and glenoid rim restoration. Complications and the nonanatomic nature of the procedure have spurred research on graft sources. The iliac crest is preferred for autogenous structural grafts. Tricortical, bicortical, and J-bone grafts have shown promising results despite the historical association of Eden-Hybinette procedures with early degenerative joint disease. Allogeneic osteochondral grafts may minimize the risk of arthropathy and donor site morbidity. Tibial plafond and glenoid allografts more closely match the native glenoid geometry and restore the articular chondral environment, compared with conventional grafts. Graft availability, cost, risk of disease transmission, and low chondrocyte viability have slowed the acceptance of osteochondral allografts.
Background The purpose of this study was to determine the risk of periprosthetic infection after primary shoulder arthroplasty (SA) in patients undergoing previous nonarthroplasty shoulder surgery ...compared with those without previous surgery. Materials and methods All patients undergoing primary SA at our institution between 1970 and 2012 were included in this study. The cohort consisted of 4577 patients treated with 2890 total SAs, 1233 hemiarthroplasties, and 454 reverse SAs; 813 (18%) patients had undergone prior nonarthroplasty shoulder surgery on the operative side. Patients with and without previous surgery were compared for postoperative periprosthetic infection. Univariate and multivariable analyses were used. Results Deep postoperative infection of the shoulder was diagnosed in 68 patients (1.49%). Of the 813 patients who had undergone previous surgery, 20 (2.46%) developed a deep postoperative infection. However, of the 3764 patients who did not have previous shoulder surgery, 48 patients (1.28%) sustained deep shoulder infection. This difference was significant in both the univariate ( P = .0094) and multivariate analyses ( P = .0390). In addition, older age and female gender were significantly associated with a lower risk of deep postoperative infection ( P = .0150 and P = .0074, respectively). A higher number of previous surgeries was also significantly associated with an increased risk of deep postoperative infection ( P = .0272). Conclusions The risk of infection after primary SA is significantly higher in patients with a history of prior non–arthroplasty-related surgery. This finding should be discussed with the patients before their surgery, and potential preoperative and intraoperative workup should be undertaken to identify at-risk patients.
Revision of a shoulder arthroplasty to a reverse shoulder arthroplasty in the presence of glenoid bone loss is especially challenging. The purpose of the present study was to determine the ...complications and results of glenoid bone-grafting in revision to a reverse shoulder arthroplasty.
Between 2005 and 2010, 143 consecutive reverse shoulder arthroplasties performed as revision procedures were performed at our institution. Glenoid bone-grafting was performed in forty-one shoulders (29%), with 98% (forty) that had follow-up of more than two years (mean, 3.1 years). The 102 patients who did not undergo grafting served as a control group.
Seven patients (18%) required another revision surgery because of glenoid loosening (four patients), instability (two patients), or infection (one patient). The two and five-year implant survival rate free of revision for shoulders that had glenoid bone-grafting was 88% and 76%, respectively, which was lower than that for patients who had not required glenoid bone-grafting. The survival rate free of radiographic glenoid loosening at two and five years for the shoulders that had bone-grafting was 92% and 89%, respectively, which was worse than that for those that had not had glenoid bone-grafting. Patients had significant pain relief and improvement in their shoulder range of motion, and they had an increased level of satisfaction compared with the preoperative status. Increased rates of glenoid loosening were seen in patients who had an increased body mass index, an implant with a lateral center of rotation, a previous total shoulder replacement (versus hemiarthroplasty), and in those who were smokers.
Although there were relatively high rates of glenoid loosening and reoperation at mid-term follow-up, glenoid reconstruction with bone graft in the revision setting was able to relieve pain and restore shoulder function and stability.
Abstract Tendon transfer options to reconstruct a massive irreparable posterior-superior rotator cuff tear include latissimus dorsi, teres major, or lower trapezius transfer. We previously described ...the lower trapezius transfer using a 2-incision approach, which includes a medial incision to harvest the lower trapezius and lateral transacromial incision to expose the rotator cuff and then perform the transfer through a deep tunnel connecting these 2 sites. In this report, we describe an arthroscopic-assisted technique of lower trapezius transfer augmented with an Achilles tendon allograft to reconstruct an irreparable posterior-superior rotator cuff tear.
