Clinical Outcomes of Percutaneous Biliary Endoscopy: A 7-Year Single-Institution Experience.

PURPOSE: To evaluate safety and effectiveness of percutaneous biliary endoscopy (PBE) performed on patients ineligible for surgery or endoscopic retrograde cholangiopancreatography. MATERIALS AND METHODS: Retrospective review was conducted for all patients who underwent PBE at a single academic institution between June 2013 and February 2020; 39 patients underwent 58 choledochoscopy sessions, and 21 patients underwent 48 cholecystoscopy sessions. Choledochoscopy indications included stone removal (23 of 39 patients) or biliary stenosis evaluation (19 of 39 patients). Cholecystoscopy indications included calculous cholecystitis (18 of 21 patients) and symptomatic cholelithiasis (3 of 21 patients). Technical success, procedural and fluoroscopy times, and tube-free survival were assessed. RESULTS: For all PBEs performed for stone clearance, using disposable endoscopes led to shorter mean ± SD procedural (128.7 minutes ± 56.2 vs 240.2 minutes ± 184.6; P < .01) and fluoroscopy times (10.7 minutes ± 7.9 vs 16.5 minutes ± 12.0; P = .01) than using reusable endoscopes. Increasing institutional experience was associated with reduced procedural time (ß = -56.73; P < .001). Choledochoscopy technical success was 94.8% with 1 adverse event of bile duct perforation with bile leak requiring drainage. For patients with choledocholithiasis, biliary drains were removed in 14 (60.9%) patients, with a mean tube-free survival of 22.1 months ± 23.8. For cholecystoscopy, technical success was 93.8% with no adverse events. Cholecystostomy tubes were removed in 15 (71.4%) patients, with a mean tube-free survival of 7.5 months ± 8.8. CONCLUSIONS: This study supports PBE as a safe and feasible option for nonsurgical patients or those with altered anatomy precluding endoscopic retrograde cholangiopancreatography. Moreover, PBE may result in tube-free survival.

Wrist Arthrodesis for Failed Total Wrist Arthroplasty.

PURPOSE: Treatment options for failed total wrist arthroplasty include implant revision, resection arthroplasty, and arthrodesis. Variable results associated with different techniques have been reported for arthrodesis and the procedure has substantial technical challenges, including restoration of wrist height, obtaining stable fixation, and achieving bony fusion. This study evaluates the radiographic results of a surgical technique for conversion of a failed arthroplasty to an arthrodesis. METHODS: A retrospective chart and radiograph review was performed in 20 wrists in 18 patients in whom conversion to an arthrodesis was performed using a contoured cancellous femoral head structural allograft and a wrist arthrodesis plate. Supplemental demineralized bone matrix combined with corticocancellous allograft chips was also used in 15 wrists. Median age at arthrodesis was 61 years (range, 45-78 years), and median follow-up was 34 months (range, 4-71 months). RESULTS: Nineteen of 20 wrists fused following the index procedure at a median of 4 months (range, 3-7 months). Proximal plate loosening occurred in 1 wrist but the joint still fused at 6 months; a successful osteotomy and revision of screw fixation was done 2 years later to correct the deformity and hardware irritation in this case. Complications were otherwise limited to 1 superficial infection that resolved with intravenous antibiotics. CONCLUSIONS: This technique for conversion of a failed total wrist arthroplasty to a wrist arthrodesis is safe, effective, and versatile. Wrist deformity is corrected, wrist height can be restored, stable fixation is obtained, and a high rate of fusion is achieved despite filling large defects using structural cancellous allograft. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Postsurgical complications following distal radius volar plating in a diabetic population at short-term follow-up.

BACKGROUND: Diabetes mellitus increases the risk of complications following operative treatment of lower extremity fractures. There is little published data establishing the impact of diabetes following surgical treatment of upper extremity fractures. This investigation aimed to compare the incidence of short-term postsurgical complications following volar locked plating of distal radius fractures in patients with and without diabetes. METHODS: A retrospective matched cohort investigation of 33 diabetics matched 1:2 to 66 non-diabetics was performed, accounting for age, gender, fracture type, and smoking status. Electronic medical records and radiographs were reviewed for all major and minor postsurgical complications. Demographic characteristics, postoperative radiographic parameters, and final range of motion were also compared. Mean follow-up was 5.3 ± 8.2 and 5.5 ± 7.8 months for diabetics and non-diabetics, respectively. RESULTS: The diabetic cohort had a significantly higher overall complication rate with 24 postsurgical complications affecting 12 patients (36 %) compared to 16 complications affecting 12 patients (18 %) in the non-diabetic cohort. There was no difference in the incidence of major complications requiring operative intervention. Minor complications were significantly more common in the diabetic group and were largely accounted for by peripheral neuritis with an incidence of 30 %. Final radiographic outcomes and range of motion were similar. CONCLUSIONS: Diabetics experienced a greater incidence of minor postsurgical complications following volar locked plating of distal radius fractures when compared to a matched, control population. The difference in outcomes is largely accounted for by the increased incidence of peripheral neuritis among diabetics. Diabetic patients should be counseled pre-operatively regarding their elevated risk profile.

MCP arthrodesis using an intramedullary interlocking device.

BACKGROUND: A variety of metacarpophalangeal joint (MCPJ) arthrodesis techniques have been described for the treatment of symptomatic arthritis and instability of the thumb MCPJ including K wire fixation, tension-band arthrodesis, plate fixation, intramedullary screw, and other intramedullary devices. This study presents a retrospective review of one surgeon's initial series of patients undergoing thumb MCP arthrodesis using an intramedullary compression device with a fixed angle of 25°. METHODS: A retrospective chart and radiographic review of patients treated for thumb MCP arthrodesis using the intramedullary device was performed. Final radiographs were evaluated for arthrodesis angle, bony fusion, and implant fixation. Any complication found during surgery or the follow-up period was noted. RESULTS: In this study, 17 patients were reviewed. Indications for surgery were osteoarthritis (five patients), rheumatoid arthritis (three patients), MCP instability alone (seven patients), and post-traumatic conditions (two patients). Of these, 12 patients had a simultaneous trapeziometacarpal (TMC) soft tissue arthroplasty. Mean follow-up was 4.9 months. All 17 patients had clinical and radiographic evidence of fusion at an average of 7.9 weeks, with an average fusion angle of 24.4°. There were no hardware complications, no infections, no revisions, and no indications for hardware removal. DISCUSSION: Our study results indicate the technique promotes rapid union at a precise angle, provides strong fixation that does not require prolonged immobilization, does not cause hardware irritation, and can be used in conjunction with other procedures including TMC arthroplasty when MCP arthrodesis is indicated for joint instability.

Reconstruction for anterior sternoclavicular joint dislocation and instability.

BACKGROUND: Sternoclavicular joint (SCJ) instability is relatively rare. Surgical treatment may be considered for severely displaced dislocations or symptomatic recurrent anterior instability. The purpose of this study was to describe an SCJ ligament reconstruction technique and retrospectively evaluate its safety and effectiveness for treating anterior SCJ dislocations and instability. MATERIALS AND METHODS: A retrospective review of demographics, medical history, injury characteristics, and pretreatment pain and functional levels was performed. A soft-tissue graft woven in a Roman numeral X pattern through clavicular and sternum subcortical bone tunnels was used. Patients were evaluated with postoperative visual analog scale (VAS) and functional scores, and their ability to return to normal preoperative sports and activities was determined. RESULTS: Six patients were evaluated with a mean follow-up of 40 months (range, 24.5-58 months). Injury mechanisms included acute trauma (3 patients), minor trauma (1 patient), and chronic atraumatic instability (2 patients). The mean preoperative symptom duration was 11 months (range, 0.5-27.5 months). Autograft hamstring graft was used in all cases with no resulting surgical complications. All 6 patients had full range of motion with no instability after treatment. Five patients had no pain (0 of 10 on VAS), whereas one patient had mild pain (1 to 3 of 10 on VAS). All 6 patients had improved functional scores. All returned to preoperative activities and participation in sports. No recurrent instability occurred. In 1 case, failure occurred at 4 years with recurrent pain, and revision was performed. CONCLUSIONS: The results of our study indicate that reconstruction for anterior SCJ dislocation is safe with results comparable to previously described surgical stabilization techniques. This technique provides a surgical treatment option for symptomatic anterior SCJ dislocation and instability.
