Summary: Using autologous fibular grafting to reconstruct reverse Hill-Sachs defect can restore the spherical contour of the humeral head and provide a smooth biological articular surface. While offering advantages of availability, simplicity, safety, and bone preservation, further long-term clinical studies are needed to verify the outcomes of this technique.

Summary: This study evaluated the functional outcomes of patient treatment using an allograft for chronic locked posterior shoulder dislocation with a bony defect. The results showed that the use of bone allografts yielded good results for patients with humeral head defects involving 25-50% of the articular surface.

Summary: This study evaluated the clinical outcome of surgical treatment for posterior fracture dislocations of the proximal humerus, specifically focusing on humeral head preservation. The results showed good to very good clinical results for humeral head preserving treatment, with better outcomes observed in patients with impression type fractures compared to those with surgical neck fractures.

Summary: Segmental reconstruction of the humeral head with fresh-frozen osteochondral allografts provides good to excellent clinical outcomes for patients with locked posterior shoulder dislocations, with low-grade osteoarthritis development and minimal allograft resorption. This joint-preserving procedure showed no cases of failure in this study.

Summary: In this retrospective study of 12 patients with chronic locked posterior shoulder dislocation, the clinical outcomes of the McLaughlin procedure or modified McLaughlin procedure were satisfactory, with a high probability of no recurrence postoperatively. However, there were still cases of avascular necrosis of the humeral head and glenohumeral osteoarthritis.

Summary: Shoulder hemiarthroplasty (HA) is rarely used for complex proximal humeral fractures due to the unpredictable healing of the greater tuberosity (GT). Although reverse shoulder arthroplasty (RSA) is gaining popularity, there are concerns about revision failure and its application in young populations. The use of HA in fracture treatment is still debatable.

Summary: The study investigated the long-term outcomes of radial head arthroplasty in complex elbow injuries, finding that the procedure had a certain effect on improving functional status after 10 years, but also raised concerns about periprosthetic osteolysis. Continuous follow-up is needed, with consideration for further surgical intervention.

Summary: In this retrospective study, the modified McLaughlin technique showed good mid- and long-term functional outcomes for chronic LPDS. Range of motion significantly improved postoperatively, along with improvements in functional outcome measures. However, delayed diagnosis (> 6 months) led to worse clinical outcomes in some cases.

Summary: This study evaluated the clinical and radiological outcomes of patients with humeral head posterior fracture dislocation treated with an open posterior reduction and fixed with blocked threaded wires. The results showed good pain relief, excellent reduction, and no complications such as avascular necrosis or arthritis progression. Therefore, this treatment method is considered satisfactory.

Summary: This study evaluated the outcomes and survivorship of osteochondral allograft (OCA) transplantation to the humeral head in patients with osteochondral defects for at least 10 years of follow-up. The results showed that OCA transplantation can result in acceptable long-term function for patients.

Summary: The study found a significant muscle volume imbalance in the transverse force couple, with the subscapularis muscle showing higher volume compared to the infraspinatus and teres minor muscles in patients with PSSH. This novel finding may support the theory that transverse force couple imbalance is associated with PSSH.

Summary: This study compared the outcomes and complications of humeral head replacement (HHR) and total shoulder replacement (TSR) in patients with osteonecrosis of the humeral head (ONHH). The findings showed satisfactory clinical and radiological outcomes with implant longevity for both HHR and TSR, with a greater abduction angle observed in the HHR group compared with the TSR group.

Summary: This study describes a variant of the PCHAP flap based on a constant musculocutaneous perforator. The cadaveric study showed the presence of a stable musculocutaneous perforator originating from the PCHA. In the case series, patients who underwent reconstruction using the musculocutaneous perforators of the PCHA had good postoperative outcomes.

Summary: This study reported the mid-term clinical and radiographic results of aLDT for irreparable posterosuperior RCTs in 31 consecutive patients. At final follow-up, 13% of patients underwent revision to RTSA due to untreatable pain, with higher preoperative pain levels associated with revision. Patients with failed previous RCRs showed significantly inferior results compared to those without previous repair.

Summary: The study evaluated factors associated with success or failure of using ICBG to restore shoulder stability after Latarjet failure. Salvage ICBG procedures failed in 7 out of 16 patients, with success typically seen in patients with clear graft-related factors from the initial Latarjet procedure. Patients with unclear instability symptoms, subscapularis insufficiency, inferior subluxation, uncontrolled seizures, or psychological disorders may not be suitable candidates for salvage ICBG, highlighting the importance of careful patient selection for both the initial Latarjet procedure and salvage ICBG.

Summary: This study examined the clinical and radiographic outcomes of reverse total shoulder arthroplasty (RTSA) for glenoid deficiency. It was found that patients with bony deficient glenoids had a surgical site complication and revision rate of 17% and 7% respectively, but overall satisfaction scores and clinical outcomes were comparable to patients with normal glenoid bone stock.

Summary: Loss of functional internal rotation (fIR) after reverse total shoulder arthroplasty (RTSA) is common but not primarily related to a deficit in internal rotation. The study found that functional internal rotation after RTSA requires at least 40 degrees of shoulder extension, and if fIR is unsatisfactory despite 40 degrees of extension, passive restriction of internal rotation in full extension is the limiting factor. It is crucial to preserve or restore active shoulder extension for activities involving internal rotation.

Summary: This study aimed to assess the impact of preoperative radiotherapy on soft tissue sarcoma treatment. Results showed that preoperative radiotherapy significantly increased the minimal distance between the tumor and vessels, high-grade tumors had a significant increase in volume after irradiation, and myxoid liposarcoma subtype demonstrated a significant volume reduction in all cases.

Summary: This study followed patients who underwent RSA for up to 5 years and found significant improvements in CS, SSV, flexion, and abduction postoperatively, despite no improvement in ER. The radiographic progression of notching and unchanged ER did not affect the postoperative functional outcomes over the 5-year period.

Summary: This study compared the clinical outcomes of operative and conservative treatment for patients with acromial or scapular spine fractures after reverse total shoulder arthroplasty (RTSA). The results showed no significant differences between the two treatment methods in terms of Constant score, subjective shoulder value, or range of motion. However, both treatment options yielded inferior results compared to RTSA without postoperative acromial fractures. Conservative treatment may be the preferred option for acromial fractures after RTSA until better surgical methods are developed.

Summary: The pilot study evaluated the treatment outcomes of glenohumeral osteoarthritis patients, showing high early failure rates and only a few patients achieving satisfactory clinical results, which were associated with advanced glenoid erosion. Therefore, this surgical approach did not demonstrate superior outcomes compared to traditional procedures.
