Arthroscopic biceps tenodesis using press-fit bony plug: a case series study.

PURPOSE: To assess the feasibility, operative time, clinical outcomes, possible complications, and failure rates of all-through arthroscopic biceps tenodesis using press-fit bony plug technique. METHODS: This prospective case series study involved 30 skeletally mature patients with long head of biceps pathology (tendinitis after failure of conservative treatment, subluxation, dislocation, or tendon tears). All patients were followed up for 24 months at least. RESULTS: Twenty-nine patients regained full shoulder and elbow range of motion; one case suffered from reflex sympathetic dystrophy. There was a significant improvement in the constant, ASES, and VAS scores when comparing the pre-operative and post-operative values. The average biceps strength was 96% compared to the opposite healthy side. No cases were complicated by neuro-vascular deficits or failure of the tenodesis. CONCLUSION: Press-fit biceps tenodesis is safe and accessible with low economic demands. We recommend this technique to be used more often when addressing patients with long head of biceps pathologies. REGISTRATION DATA: Registration number: N-1562023.

Conservative treatment versus transverse pinning in fifth metacarpal neck fractures in active adults: a randomized controlled trial.

PURPOSE: Compare two simple ways for treating boxer's fractures in active adults; conservative management by ulnar gutter slab and transverse pinning in fixation of fifth metacarpal's neck fracture regarding union, functional outcomes, and complications. PATIENTS AND METHODS: Ninety patients with fifth metacarpals' neck fractures with palmar angulation (30-70°) were managed either conservatively by an ulnar gutter slab or surgically by transverse pinning technique from January 2020 to December 2021. Only 84 patients completed a 1-year follow-up. Patients with old, open, or mal-rotated fractures were excluded. The block-randomization method was used to create equal groups. Patients were evaluated clinically and radiologically every 2-3 weeks until union, then at 6 and 12 months. Functional assessment at the final visit was done using the quick DASH score, total active motion (TAM), and total Active Flexion (TAF). RESULTS: The mean radiological union time for the conservative group in this study was 7.76 weeks, while for the transverse pinning group, it was 7.38 weeks. There was no statistically significant difference between the two techniques regarding union rates and functional outcomes. All patients returned to their pre-injury jobs and level of activity. CONCLUSION: Both conservative management in ulnar gutter slab and percutaneous transverse pinning are considered effective methods in the treatment of simple extra-articular fifth metacarpal neck fractures with angulation between 30 and 70 degrees (AO: 77 A3.1). The functional and radiological results using both methods were satisfactory and statistically comparable.

Lateral malleolar fractures Weber Type A and B: does percutaneous intramedullary screw confer a solid alternative to the traditional neutralization plate?

PURPOSE: To compare the clinical results, complication rates, and radiographic outcome between both methods of fixation of lateral malleolar fractures: lateral neutralization plates and intramedullary fully threaded screws. PATIENTS AND METHODS: This prospective case series study involved 73 patients with fractured lateral malleolus of type A, B according to Weber classification, to whom internal fixation was performed by either lateral plate and screws construct (Group A) or intramedullary screw (Group B). All patients were followed up for 12 months at least, with an average follow-up time of 12.7 months. RESULTS: There was no significant difference in the functional outcome score between both groups. The intramedullary screw group had a significantly shorter operative time and time to full union (P<0.001 and =0.006 respectively). There was a relatively higher accuracy of reduction with the plate fixation group, but it was statistically insignificant. There was a relatively fewer complication rate with the use of intramedullary screw fixation compared to plate fixation. CONCLUSION: The use of intramedullary fixation is a good alternative for plate fixation in low fibular fractures (Weber A and B). Although plate fixation provides an optimal anatomic reconstruction of the fractures, intramedullary fixation may have a lower risk of complications.

Are small-diameter intramedullary nails enough for treating simple diaphyseal tibial fractures? A comparative study between small versus large nails.

PURPOSE: The aim of our study was to compare the results of using small-diameter versus large-diameter interlocking reamed intramedullary nails in treatment of simple tibial shaft fractures. METHODS: This prospective randomized control trial involved 60 patients, divided into two groups, Group A (Small IMN) (10 mm in males and 9 mm in females) and Group B (Large IMN) (12 mm in males and 11 mm in females). All patients were followed up for at least 1 year. RESULTS: The mean operative time in Group A was 79 min versus 94.6 min in Group B. The mean time of radiological exposure in Group A was 2.27 min compared to 3.73 min in Group B. The mean union time in Group A was 15.2 weeks, while in Group B, the mean union time was 12.8 weeks. Implant failure (screw breakage or nail breakage) or nonunion did not occur in any case in the two groups. CONCLUSION: Small IMN showed comparable clinical and radiological results to large IMN with lesser operative and radioscopic time. We can recommend that small IMN should be used more often in treating simple stable tibial fractures.

Arthroscopic Assisted Reduction and Internal Fixation of Tibial Plateau Fractures.

BACKGROUND: Tibial plateau fractures present an important entity in orthopaedic fractures. Arthroscopic-assisted reduction and internal fixation is a good alternative to ORIF as it has the advantage of direct visualisation of the articular surface of the plateau, direct assessment of the reduction of the articular surface, and managing any associated intra-articular pathology. AIM: Our study aim is to determine the results of arthroscopic assisted reduction and internal fixation of tibial plateau fractures. METHODS: This study involved 25 patients with tibial plateau fractures presenting to the emergency department of Cairo University Hospitals between the periods of November 2016 and May 2017. The patients were followed up for an average of 14 months (11-18 months). According to Schatzker's classification, five patients had type I, eleven had type II, and nine patients had type III fractures. RESULTS: The average time to full union in Schatzker type I was 9.1 weeks, in type II was 10.2 weeks, and in type III it was 9.4. The mean clinical Rasmussen score among the 25 patients was 26 (range, 24-30). A group of 19 patients (76%) had excellent results, (4 type I, 8 types II, and 7 types III) 6 patients (24 %) had good results (1 type I, 3 types II, 2 types III). Radiologic results were excellent in (14 cases) 56.0% and good results (11 cases) 44%. CONCLUSION: Arthroscopic assisted reduction and fixation of tibial plateau fractures have the advantages of checking the adequacy of reduction, avoiding the need for detachment of the meniscus, and allowing for accurate diagnosis and management of associated knee injuries. Therefore, we recommend that arthroscopic assisted reduction and fixation of tibial plateau fractures should be used more often.
