Functional performance of the upper limb and the most common boxing-related injuries in male boxers: a retrospective, observational, comparative study with non-boxing population.

BACKGROUND: To investigate the functional status and recording the most common injuries of the upper limb in male Greek boxing squad in comparison to the general population. METHODS: A retrospective injury surveillance study using an electronic questionnaire was performed in 2021. The questionnaire was sent to male members of the Greek Boxing Federation and consisted of three parts. Demographic data, functional status scales, training conditions, hours of training, the location and description of upper limb injuries and whether the injury occurred during competition or training and also whether it was a new or a recurrent one were gathered. The same questionnaire was sent to non-boxer males (military recruits), but without asking them to report any training parameters. Inclusion criteria were age < 35 years-old for all participants and no involvement in martial arts for the control group. Also, all participants (boxers and non-boxers) completed the Patient Rated Wrist Evaluation (PRWE) scale and the Quick Disabilities of Arm, Shoulder and Hand (quick-DASH) score. RESULTS: The final study cohort was consisted of 62 elite or amateur boxers and 75 non-boxer males, less than 35 years old. The quick-DASH score was found to be significantly lower (better) in boxers in comparison to the general population (15.65 ± 10.25 vs. 12.55 ± 8.62; p = 0.020) whereas the PRWE score was similar in both groups (9.25 ± 14.96 vs. 8.61 ± 13.05; p = 0.843). Physical therapy sessions, thumb injuries and boxer's knuckle were also found to be significantly higher in the boxers group. On the other hand, upper limb surgeries were significantly less in the boxers group. Finally, the size of boxing gloves was associated to the number of finger fractures, thumb injuries and ulnar sided wrist pain in boxers. CONCLUSIONS: Although a controversial sport, boxing appears to have no long-term consequences to the upper limb function, especially regarding hand performance. The size of gloves during heavy bag training was found to be an aggravating factor for hand injuries.

Neglected Rupture of the Patellar Tendon After Fixation of Tibial Tubercle Avulsion in an Adolescent Male Managed With Ipsilateral Semitendinosus Autograft Reconstruction.

The combination of a tibial tubercle fracture with patellar tendon avulsion in adolescents is an extremely rare injury that needs to be managed properly. Herein, we report the case of a 15-year-old boy who presented to our department two months after sustaining a tibial tubercle fracture that had been managed with mini-open reduction and internal fixation in another hospital; he had restricted range of motion and complete inability to extend his knee. Clinical and radiological investigations revealed a neglected avulsion of the patellar tendon with marked scarring and severe retraction. The patient underwent patellar tendon reconstruction using the ipsilateral semitendinosus tendon that passed through separate tunnels in the patella and proximal tibia. The postoperative course was uneventful, and one year later the patient had a satisfactory range of motion and a Lysholm score of 90. To our knowledge, a neglected patellar tendon avulsion after tibial tubercle fracture fixation has been reported only once in the literature. The reconstruction of the patellar tendon using an ipsilateral semitendinosus autograft is an excellent surgical technique, especially when severe tendon retraction has occurred.

Multimodal analgesia protocol for pain management after total knee arthroplasty: comparison of three different regional analgesic techniques.

OBJECTIVES: To evaluate three different analgesic techniques, continuous epidural analgesia (EA), continuous intra-articular (IA) infusion analgesia and continuous femoral nerve block (FNB) in postoperative pain management, length of hospital stay (LOS), and time of patient mobilization after total knee arthroplasty (TKA). METHODS: Seventy-two patients undergoing TKA were randomly allocated into three groups according to the analgesic technique used for postoperative pain management. Group EA patients received epidural analgesia (control group), group IA received intra-articular infusion and group FNB received femoral nerve block. RESULTS: Upon analyzing the Numerical Rating Scale (NRS) scores at rest, at passive and active movement, up to 3 days postoperatively, we observed no statistically significant differences at any time point among the three groups. Similarly, no association among these analgesic techniques (EA, IA, FNB) was revealed regarding LOS. However, significant differences emerged concerning the time of mobilization. Patients who received IA achieved earlier mobilization compared to FNB and EA. CONCLUSIONS: Both IA and FNB generate similar analgesic effect with EA for postoperative pain management after TKA. However, IA appears to be significantly more effective in early mobilization compared to EA and FNB. Finally, no clinically important differences could be detected regarding LOS among the techniques studied.
