Mid-term and Long-term Functional and Radiographic Results of 13 Surgically Treated Adolescent Capitellum Fractures.

BACKGROUND: Capitellum fractures are rare in adolescents, and information in literature is still limited. The purpose of this study was to report the mid-term and long-term functional and radiographic results of 13 surgically treated adolescent capitellum fractures in a level I trauma center. METHODS: This retrospective study included patients aged 10 to 16 years, who underwent surgery for a capitellum fracture and were followed up for at least 12 months. Fractures were classified according to the McKee modification of the Bryan and Morrey classification, and elbow arthritis was classified using the Broberg and Morrey system. Functional outcomes were assessed with the Mayo Elbow Performance Index (MEPI) and the Turkish-language version of the shortened version of the Disabilities of Arm, Shoulder, and Hand (QuickDASH) scale. RESULTS: The mean time to surgical intervention was 4.5 days (range, 1 to 18 d). The mean flexion-extension range of motion arc was measured as 115 (range, 45 to 150) degrees. The mean restriction for extension and flexion compared with the uninjured side was measured as 10.7 (range, 0 to 45) and 11.5 (range, 0 to 45) degrees, respectively. The mean MEPI was 87.7 points (range, 50 to 100 points) with 9 patients as excellent, 1 good, 1 fair, and 2 poor results. The mean QuickDASH score was 11 (range, 0 to 57). The mean MEPI score was 95.6 and 75 and the mean QuickDASH score was 2.62 and 25.0 for early surgery group (≤3 d) and late surgery group (>3 d), respectively (P=0.073, 0.024). Elbow joint contracture developed in 4 patients. Implant removal and open release of joint contracture was applied to 2 patients. Elbow arthritis of grade 3 was observed in 2 patients and grade 2 in 1 patient. CONCLUSIONS: Capitellum fractures may be easily missed on conventional radiographs, if not suspected. Delayed diagnosis may lead to a worsening of the functional outcomes. Computerized tomography is helpful in the determination of these fractures. Early diagnosis and a well-performed surgery is essential for successful outcome. LEVEL OF EVIDENCE: Level IV-case series.

Single-incision lateral approach for triple arthrodesis.

BACKGROUND: Triple arthrodesis is a powerful hindfoot corrective procedure involving fusion of the talonavicular (TN), calcaneocuboid (CC), and subtalar (ST) joints. A 2-incision approach, a single-incision medial triple arthrodesis, and a single-incision medial double arthrodesis are well described. We present a single-incision lateral approach to triple arthrodesis. METHODS: We retrospectively reviewed 70 patients who underwent triple arthrodesis at our institution from 2007 to 2011. Patients had either double-incision (n = 33) or single-incision lateral (n = 37) triple arthrodesis. A single surgeon performed all procedures. The most common diagnosis was stage III planovalgus deformity. Deformity correction, union rate, time of surgery, complications, wound healing, reoperations, and pre- and postoperative visual analog scale (VAS) pain scores were analyzed for both groups. RESULTS: There were no statistical differences in deformity correction, wound healing, complications, reoperations, or improvement in VAS pain scores. Operation time was significantly shorter in the single-incision lateral group (86 minutes vs 95 minutes, P = .0395). There was no difference in union rates with regard to the TN, ST, or CC joints. Five patients had radiographic nonunions of the CC joint between both groups. CONCLUSIONS: This is the first study that presents outcomes of a single lateral approach for triple arthrodesis. The single-incision approach was faster. The low rate of symptomatic nonunions suggests that fusion of the CC joint may not be important in symptomatic relief or deformity correction. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

Clinical outcomes of endoscopic carpal tunnel release in patients 65 and over.

PURPOSE: To examine outcomes of endoscopic carpal tunnel release (ECTR) in patients 65 and older. We hypothesized that this population could expect relief of pain, night pain/numbness, and numbness. METHODS: A retrospective review was conducted of all patients 65 years of age and over who had ECTR for nerve conduction study-confirmed carpal tunnel syndrome (CTS) from October 2007 to July 2010. The charts were reviewed for demographic data, symptoms and physical findings, patient satisfaction, and 3 patient-reported outcome scores. Preoperative and postoperative results for pain, night pain/numbness, and numbness were compared. Logistic regression analysis was used to assess whether age influenced symptom resolution. Boston carpal tunnel, Short Form-36 and Disabilities of the Arm, Shoulder, and Hand scores were compared between patients with mild, moderate, or severe CTS. RESULTS: A total of 78 patients had ECTR. Their ages ranged from 65 to 93 years (mean, 73 y). Before surgery 69% of patients had constant numbness. Night pain/numbness was present in 65 patients before surgery, and 61 had complete resolution. All 70 patients who presented with pain reported complete relief by the 6-month follow-up. Following ECTR, the average Boston carpal tunnel symptom severity, functional status, and Disabilities of the Arm, Shoulder, and Hand scores were 1.5,1.5, and 13, respectively. At final evaluation, 79% of patients were very satisfied or satisfied with their outcome. A significant number of patients were found to have improvement in pain, night pain/numbness, and numbness following ECTR. CONCLUSIONS: This study has demonstrated relief of symptoms in a statistically significant number of patients following ECTR. We found that preoperative CTS severity, based on nerve conduction study result, did not significantly correlate with patient outcome following ECTR. Advanced symptoms at presentation do not preclude symptom resolution and should not be a contraindication to ECTR. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.

Reverse total shoulder arthroplasty in obese patients.

PURPOSE: To determine function and complications after reverse total shoulder arthroplasty (RTSA) in obese patients compared with a control group of nonobese patients. METHODS: Between 2005 and 2011, we performed 76 RTSAs in 17 obese, 36 overweight, and 23 normal weight patients, based on World Health Organization body mass index classification. We reviewed the charts for age, sex, body mass index, date of surgery, type of implant, type of incision, length of stay, comorbidities, surgical time, blood loss, American Society of Anesthesiologists score, shoulder motion, scapular notching, and postoperative complications. Complications and outcomes were analyzed and compared between groups. RESULTS: Reverse total shoulder arthroplasty in obese patients was associated with significant improvement in range of motion. Complication rate was significantly greater in the obese group (35%), compared with 4% in the normal weight group. We found no significant differences between scapular notching, surgical time, length of hospitalization, humeral component loosening, postoperative abduction, forward flexion, internal and external rotation, pain relief, or instability between groups. CONCLUSIONS: Our results show that obese patients have significant improvement in motion after RTSA but are at an increased risk for complication. Obesity is not a contraindication to RTSA, but obese patients need to understand fully the increased risk of complication with RTSA. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.

Treatment of pertrochanteric fractures (OTA 31-A1 and A2): long versus short cephalomedullary nailing.

OBJECTIVES: To retrospectively compare the clinical outcomes in patients with pertrochanteric femur fractures without subtrochanteric extension (OTA 31-A1 and A2) after treatment with short or long cephalomedullary nails. DESIGN: Retrospective study. SETTING: Academic level I trauma center. PATIENTS: Two hundred eighty three adult patients presenting with simple or multifragmentary pertrochanteric femur fractures (OTA 31-A1 and A2) between 2004 and 2009 qualified for inclusion in this study. INTERVENTION: One hundred patients were treated with a short cephalomedullary nail and 183 with a long cephalomedullary nail. MAIN OUTCOME MEASUREMENTS: Patient demographics and medical comorbidities were recorded for each patient via an electronic medical record. Treatment-related variables including the American Society of Anesthesiologists (ASA) score, duration of surgery, volume of intraoperative blood loss, need for blood products, treatment-related complications, and mortality were recorded and compared between the short and long nail groups. RESULTS: There were no significant difference between treatment modalities, complication, and reoperation rates for the 2 groups. Treatment with a long nail resulted in subtle increases in procedure time and blood loss. CONCLUSIONS: No differences in the union and complication rates between the 2 groups were identified, suggesting that long nails offer no advantage compared with short nails for stabilizing simple and multifragmentary pertrochanteric femur fractures without subtrochanteric extension (OTA 31-A1 and A2). LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
