Intramedullary Headless Screw Fixation for Metacarpal Fractures.

Multiple techniques have been proposed for metacarpal fracture fixation, including percutaneous Kirschner-wires, interfragmentary screws, plate and screw constructs, intramedullary (IM) nails, and cannulated IM headless screws. Each of these treatment options has its proposed advantages and disadvantages, and there remains no consensus on the optimal mode of treatment. We describe a technique of retrograde IM headless screw fixation for extra-articular metacarpal fractures.

Iatrogenic Nerve Palsy Occurs With Anterior and Posterior Approaches for Humeral Shaft Fixation.

OBJECTIVE: To determine if surgical approach impacts the rate of nerve palsy after plate fixation of humerus shaft fractures and whether or not iatrogenic nerve palsy recovers in similar ways to preoperative palsy. DESIGN: Retrospective. SETTING: Two trauma centers. PATIENTS: Patients 18+ years of age with nonpathologic, extra-articular humerus shaft fractures (OTA/AO 12A/B/C and 13A2-3) treated with plate fixation. INTERVENTION: Plate fixation of humerus shaft fractures, from 2008 to 2016. MAIN OUTCOME MEASUREMENT: Rate of iatrogenic nerve palsy by a surgical approach and injury characteristics. RESULTS: Two hundred sixty-one humeral shaft fractures were included. The rate of preoperative palsy was 19%. Radial nerve palsy (RNP) was present in 18%. Iatrogenic RNP occurred in 12.2% and iatrogenic ulnar palsy in 1.2%. Iatrogenic palsy occurred in 15.6% of middle and 15% of distal fractures, with fracture location significantly different in those developing RNP (P = 0.009). Iatrogenic RNP occurred in 7.1% of anterolateral, 11.7% of posterior triceps-splitting, and 17.9% of posterior triceps-sparing approaches (P = 0.11). Follow-up data were available for 139 patients at an average of 12 months. Preoperative RNP resolved less often than iatrogenic RNP, in 74% versus 95% (P = 0.06). Time to resolution was longer for preoperative RNP, at 5.5 versus 4.1 months (P = 0.91). Twenty-two percent with preoperative RNP underwent tendon transfer or wrist fusion, versus 0% after iatrogenic RNP (P = 0.006). CONCLUSION: Iatrogenic RNP is not uncommon with humeral fracture fixation and occurs at similar rates in anterior and posterior approaches and with midshaft and distal fractures. Iatrogenic RNP had a high rate of recovery. Preoperative RNP more often requires surgery for unresolved palsy. LEVEL OF EVIDENCE: Therapeutic Level III.

Massive Rotator Cuff Tear: When to Consider Reverse Shoulder Arthroplasty.

PURPOSE OF REVIEW: The purpose of this review is to discuss the indications for reverse shoulder arthroplasty (RSA) in the treatment of massive rotator cuff tear (MCT), review the reported outcomes in the literature, and outline our approach and surgical technique for treating these patients. RECENT FINDINGS: While RSA remains a successful and well-accepted treatment for cuff tear arthropathy (CTA), management of MCT in the absence of arthritis is controversial. In this particular setting, patients best suited for RSA are elderly, lower-demand individuals with chronic, irreparable MCT, and pseudoparalysis. Age < 60, better pre-operative function and upper extremity neurologic dysfunction are potential risk factors for poor outcome with RSA in this population. Long-term follow-up studies of RSA for CTA and MCT show good functional outcomes and implant survival > 90% at 10 years. Treatment of MCT must be individualized for each patient. When patient selection is optimized, RSA is a reliable means of relieving pain and improving function with excellent success. Further investigation is necessary to better define its indications and assess the role of alternative, joint-salvaging procedures.

Massive Rotator Cuff Tears in Patients Older Than Sixty-five: Indications for Cuff Repair versus Reverse Total Shoulder Arthroplasty.

The decision to perform rotator cuff repair (RCR) versus reverse total shoulder arthroplasty (rTSA) for massive rotator cuff tear (MCT) without arthritis can be difficult. Our aim was to identify preoperative variables that are influential in a surgeon's decision to choose one of the two procedures and evaluate outcomes. We retrospectively reviewed 181 patients older than 65 who underwent RCR or rTSA for MCT without arthritis. Clinical and radiographic data were collected and used to evaluate the preoperative variables in each of these two patient populations and assess outcomes. Ninety-five shoulders underwent RCR and 92 underwent rTSA with an average followup of 44 and 47 months, respectively. Patients selected for RCR had greater preoperative flexion (113 vs 57), abduction (97 vs 53), and external rotation (42 vs 32), higher SST (3.1 vs 1.9) and ASES scores (43.8 vs 38.6), and were less likely to have had previous cuff surgery (6.3% vs 35.9%). Patients selected for rTSA had a smaller acromiohumeral interval (4.8 vs 8.7) and more superior subluxation (50.6% vs 14.1%). Similar preoperative characteristics included pain, comorbidities, and BMI. Patients were satisfied in both groups and had significant improvement in motion and function postoperatively. Both RCR and rTSA can result in significant functional improvement and patient satisfaction in the setting of MCT without arthritis in patients older than 65. At our institution, patients who underwent rTSA had less pre-operative motion, lower function, more evidence of superior migration, and were more likely to have had previous rotator cuff surgery.
