Aim: The aim of the study is to present our experience in the treatment of radial nerve palsy due to humeral fracture. Material and methods: During the last 4 years, we treated 10 patients with humeral fractures associated with radial nerve palsy. Seven patients were men and 3 were women (mean age 47.8 yrs, range 29–68 yrs). All fractures were closed. Three fractures were transverse, 4 were oblique and 3 were comminuted. Nerve palsy was present at admission in 8 cases while in 2 cases it appeared after closed reduction manipulations. The latter was considered as an indication for early surgical exploration. Three out of the rest 8 patients were explored because the fracture was comminuted. The remaining five patients were treated initially conservatively. In 3 of them closed reduction failed and the patients were also operated. In total, 2 of the patients were treated with closed reduction. Results: All fractures were united. During exploration no serious injury was found. All patients had complete return of nerve function within 8 months. Conclusions: Because no serious injury of the nerve was found during exploration and recovery was complete, surgical treatment could have been avoided. Conservative treatment should be the initial treatment of choice

Among the most popular techniques for the management of radial nerve palsy is the transfer of the Pronator Teres (PT) to the Extensor Carpi Radialis Brevis (ECRB), of the Flexor Carpi Radialis (FCR) to the Extensor Digitorum Communis (EDC) and of the Palmaris Longus (PL) to rerouted Extensor Pollicis Longus (EPL). This retrospective study was undertaken to assess the outcome of flexor carpi radialis transfer in the treatment of radial nerve palsy. Twenty patients with a mean age of 36 years were included in this study. Surgical management, as described above, was decided since all patients had irreparable damage to the nerve. Parameters that were assessed included range of wrist motion, dynamic power of wrist flexion and extension, and radial and ulnar deviation and function. The average follow-up was 4.5 years. Compared to a control group of 10 volunteers of similar characteristics, all patients achieved a functional range of motion and satisfactory power of wrist motion. All patients returned to their previous occupation. Transfer of Flexor Carpi Radialis tendon for irreparable radial nerve palsy yields satisfactory results. Therefore, it can be expected that patients will obtain a functional range of motion as well as an adequate strength of motion

An 83-year-old woman presented with acute weakness in her right hand and wrist extensors and swelling in the proximal right forearm. Nerve conduction studies confirmed compression of posterior introsseous nerve at the level of proximal forearm. MR imaging demonstrated the characteristics of lipoma which extended on the atero-lateral aspect of the right radius neck. The lesion was parosteal lipoma of the proximal radius causing paralysis of the posterior interosseous nerve without sensory deficit. In this case report, posterior inretosseous nerve palsy due to compression of a parostel lipoma was recovered after excision of the lipoma followed by intensive rehabilitation for six month. Surgical excision should be promptly performed to ensure optimal recovery from the nerve paralysis

Posterior interoseous nerve (PIN) syndrome is an entrapment of the deep branch of the radial nerve just distal to the elbow joint. It may result in the paresis or paralysis of the fingers and thumb extensor muscles.

We present a review of 26 cases of PIN entrapment syndrome, diagnosed an treated over a ten years period form 1996 to 2005. Their ages ranged form 12 to 57 years, they were 18 men and 8 women. The interval between, the onset or paralysis and operation ranged from 4 months to 1 year. All the patients were diagnosed preoperatively as having PIN palsy from physical examination and electromyographic (EMG) studies of the posterior interoseous innervated muscles and all were treated by operation.

The cause of compression was, ganglia in four cases, fascia thickening at the arcad of frohse in six cases, the radial recurrent vessels in three cases, lipoma in four cases, dislocated head of the radius in two cases, infamed synovium in four cases, tumour in two cases, and Intraneural Perineurioma in one case. The periods of postoperative observation were from 1 to 10 years. The paralysis recovered completely by the six postoperative months in all cases except one girl with intraneural peri-neurioma.

Three patients developed mild reflex sympathetic dystrophy which resolved with physiotherapy and auxilary blocks. Two patients developed hyperaesthesia in the distribution of the superficial radial nerve which recovered in a few weeks.

Having arrived at a diagnosis of PIN syndrome, it is important to select the correct level for the release of the radial nerve. Fair or poor results can be due to incorrect diagnosis, incomplete release or irreversible nerve injury.

Fractures of the humeral diaphysis occur in a bimodal distribution and represent 3-5% of all fractures. Presently, the standard treatment of isolated humeral diaphyseal fractures is nonoperative care using splints, braces, and slings. Recent data has questioned the effectiveness of this strategy in ensuring fracture healing and optimal patient function. The primary objective of this randomized controlled trial (RCT) was to assess whether operative treatment of humeral shaft fractures with a plate and screw construct provides a better functional outcome than nonoperative treatment. Secondary objectives compared union rates and both clinical and patient-reported outcomes. Eligible patients with an isolated, closed humeral diaphyseal fracture were randomized to either nonoperative care (initial sugar-tong splint, followed by functional coaptation brace) or open reduction and internal fixation (ORIF; plate and screw construct). The primary outcome measure was the Disability Shoulder, Arm, Hand (DASH) score assessed at 2-, 6-, 16-, 24-, and 52-weeks. Secondary outcomes included the Short Musculoskeletal Functional Assessment (SMFA), the Constant Shoulder Score, range of motion (ROM), and radiographic parameters. Independent samples t-tests and Chi-squared analyses were used to compare treatment groups. The DASH, SMFA, and Constant Score were modelled over time using a multiple variable mixed effects model. A total of 180 patients were randomized, with 168 included in the final analysis. There were 84 patients treated nonoperatively and 84 treated with ORIF. There was no significant difference between the two treatment groups for age (mean = 45.4 years, SD 16.5 for nonoperative group and 41.7, SD 17.2 years for ORIF group; p=0.16), sex (38.1% female in nonoperative group and 39.3% female in ORIF group; p=0.87), body mass index (mean = 27.8, SD 8.7 for nonoperative group and 27.2, SD 6.2 for ORIF group; p=0.64), or smoking status (p=0.74). There was a significant improvement in the DASH scores at 6 weeks in the ORIF group compared to the nonoperative group (mean=33.8, SD 21.2 in the ORIF group vs. mean=56.5, SD=21.1 in the nonoperative group; p < 0 .0001). At 4 months, the DASH scores were also significantly better in the ORIF group (mean=21.6, SD=19.7 in the ORIF group vs. mean=31.6, SD=24.6 in the nonoperative group; p=0.009. However, there was no difference in DASH scores at 12-month follow-up between the groups (mean=8.8,SD=10.9 vs. mean=11.0, SD=16.9 in the nonoperative group; p=0.39). Males had improved DASH scores at all timepoints compared with females. There was significantly quicker time to union (p=0.016) and improved position (p < 0 .001) in the ORIF group. There were 13 (15.5%) nonunions in the nonoperative group and four (4.7%) combined superficial and deep infections in the ORIF group. There were seven radial nerve palsies in the nonoperative group and five (a single iatrogenic) radial nerve palsies in the ORIF group. This large RCT comparing operative and nonoperative treatment of humeral diaphyseal fractures found significantly improved functional outcome scores in patients treated surgically at 6 weeks and 4 months. However, the early functional improvement did not persist at the 12-month follow-up. There was a 15.5% nonunion rate, which required surgical intervention, in the nonoperative group and a similar radial nerve palsy rate between groups

Paediatric supracondylar fractures are the most common elbow fracture in children, and is associated with an 11% incidence of neurologic injury. The goal of this study is to investigate the natural history and outcome of motor nerve recovery following closed reduction and percutaneous pinning of this injury. A total of 246 children who underwent closed reduction and percutaneous pinning following supracondylar humerus fractures were prospectively enrolled over a two year period. Patient demographics (age, weight), Gartland fracture classification, and associated traumatic neurologic injury were collected and analyzed with descriptive statistics. Patients with neurologic palsies were separated based on nerve injury distribution, and followed long term to monitor for neurologic recovery at set time points for follow up. Of the 246 patient cohort, 46 patients (18.6%) sustained a motor nerve palsy (Group 1) and 200 patients (82.4%) did not (Group 2) following elbow injury. Forty three cases involved one nerve palsy, and three cases involved two nerve palsies. No differences were found between patient age (Group 1 – 6.6 years old, Group 2 – 6.2 years old, p = 0.11) or weight (Group 1 – 24.3kg, Group 2 – 24.5kg, p = 0.44). A significantly higher proportion of Gartland type III and IV injuries were found in those with nerve palsies (Group 1 – 93.5%, Group 2 – 59%, p < 0 .001). Thirty four Anterior Interosseous Nerve (AIN) palsies were observed, of which 22 (64.7%) made a full recovery by three month. Refractory AIN injuries requiring longer than three month recovered on average 6.8 months post injury. Ten Posterior Interosseous Nerve (PIN) palsies occurred, of which four (40%) made full recovery at three month. Refractory PIN injuries requiring longer than three month recovered on average 8.4 months post injury. Six ulnar nerve motor palsies occurred, of which zero (0%) made full recovery at three month. Ulnar nerve injuries recovered on average 5.8 months post injury. Neurologic injury occurs significantly higher in Gartland type III and IV paediatric supracondylar fractures. AIN palsies remain the most common, with an expected 65% chance of full recovery by three month. 40% of all PIN palsies are expected to fully recover by three month. Ulnar motor nerve palsies were slowest to recover at 0% by the three month mark, and had an average recovery time of approximately 5.8 months. Our study findings provide further evidence for setting clinical and parental expectations following neurologic injury in paediatric supracondylar elbow fractures

Aims. Brace treatment is the cornerstone of managing developmental dysplasia of the hip (DDH), yet there is a lack of evidence-based treatment protocols, which results in wide variations in practice. To resolve this, we have developed a comprehensive nonoperative treatment protocol conforming to published consensus principles, with well-defined a priori criteria for inclusion and successful treatment. Methods. This was a single-centre, prospective, longitudinal cohort study of a consecutive series of infants with ultrasound-confirmed DDH who underwent a comprehensive nonoperative brace management protocol in a unified multidisciplinary clinic between January 2012 and December 2016 with five-year follow-up radiographs. The radiological outcomes were acetabular index-lateral edge (AI-L), acetabular index-sourcil (AI-S), centre-edge angle (CEA), acetabular depth ratio (ADR), International Hip Dysplasia Institute (IHDI) grade, and evidence of avascular necrosis (AVN). At five years, each hip was classified as normal (< 1 SD), borderline dysplastic (1 to 2 SDs), or dysplastic (> 2 SDs) based on validated radiological norm-referenced values. Results. Of 993 infants assessed clinically and sonographically, 21% (212 infants, 354 abnormal hips) had DDH and were included. Of these, 95% (202 infants, 335 hips) successfully completed bracing, and 5% (ten infants, 19 hips) failed bracing due to irreducible hip(s). The success rate of bracing for unilateral dislocations was 88% (45/51 infants) and for bilateral dislocations 83% (20/24 infants). The femoral nerve palsy rate was 1% (2/212 infants). At five-year follow-up (mean 63 months (SD 5.9; 49 to 83)) the prevalence of residual dysplasia after successful brace treatment was 1.6% (5/312 hips). All hips were IHDI grade I and none had AVN. Four children (4/186; 2%) subsequently underwent surgery for residual dysplasia. Conclusion. Our comprehensive protocol for nonoperative treatment of infant DDH has shown high rates of success and extremely low rates of residual dysplasia at a mean age of five years.

Aims. Ilium is the most common site of pelvic Ewing’s sarcoma (ES). Resection of the ilium and iliosacral joint causes pelvic disruption. However, the outcomes of resection and reconstruction are not well described. In this study, we report patients’ outcomes after resection of the ilium and iliosacral ES and reconstruction with a tibial strut allograft. Methods. Medical files of 43 patients with ilium and iliosacral ES who underwent surgical resection and reconstruction with a tibial strut allograft between January 2010 and October 2021 were reviewed. The lesions were classified into four resection zones: I. 1. , I. 2. , I. 3. , and I. 4. , based on the extent of resection. Functional outcomes, oncological outcomes, and surgical complications for each resection zone were of interest. Functional outcomes were assessed using a Musculoskeletal Tumor Society (MSTS) score and Toronto Extremity Salvage Score (TESS). Results. The mean age of the patients was 17 years (SD 9.1). At a mean follow-up of 70.8 months (SD 50), the mean functional outcomes were 24.2 points (SD 6.3) for MSTS and 81 points (SD 11) for TESS. The mean MSTS and TESS scores were associated with the iliac resection zone (< 0.001). Nine patients (20.9%) had local recurrence. The recurrence was not associated with the zone of iliac resection (p = 0.324). The two-year disease-free survival of the patients was 69.4%. The mean time to graft union was longer in patients with the I. 4. resection zone (p < 0.001). The complication rate was 34.9%, and nerve palsy (11.6%) was the most common. The rate of surgical complications was not associated with the resection zone. Conclusion. Reconstruction using tibial strut allograft is an efficient procedure after the resection of the ilium and iliosacral ES. Functional outcomes and complications of iliac ES depend on the resection zone, and inferior outcomes could be generally expected when more segments of the pelvic ring are resected, even if it is reconstructed.

Abstract. Background. Reconstruction following resection of sarcomas of the upper extremity with methods described in the prevalent literature may not be possible in few selected cases. We describe Surgical Phocomelia or Phoco-reduction as a method of limb salvage in such cases of extensive sarcomas of the upper limb with its functional and oncological outcomes. Methods. Evaluation of functional and oncological outcomes was performed for 11 patients who underwent surgical phocomelia or phocoreduction for extensive sarcomas of the upper limb between 2010 and 2019. Results. Mean follow-up period in the study was27.8 months. Five patients required a segmental resection including the entire humerus while 6 patients underwent segmental resection around the elbow with a mean resection length of 21.5 cm. Mean MSTS 93 score was 22 depicting a good functional outcome. Mean hand grip strength on the operated side was 62% of the contralateral side with preservation of useful hand function. Mean time to humero-ulnar union was 6.7 months. Radial nerve palsy and implant failure occurred in 1 patient each. No patient developed local recurrence while 3 patients died of metastasis. Conclusion. Surgical phocomelia is a prudent alternative to severely incapacitating amputations in situations where other reconstruction methods are not feasible

Nerve palsy occurring after elective primary total hip arthroplasty (THA) is a devastating complication because of its effect on motor strength, walking ability, potential for pain, and unexpected nature. In general, the nerve distribution involved is the peroneal branch of the sciatic nerve, and the level of involvement is usually mixed motor and sensory. Prior publications have associated limb lengthening, dysplasia and use of the posterior approach to be associated with a higher incidence of nerve palsy. In the literature, the incidence of sciatic nerve palsy is estimated to be 0.2 to 1.9%. We examined the rate of sciatic nerve palsy after THA performed by the joint replacement service at Hospital for Special Surgery between the years 1998–2013. Each case was matched with 2 controls that underwent THA and did not develop postoperative neuropathy. Controls were matched by surgical date having been within 7 days of their matched case's surgery date. Patient and surgical variables were reviewed using data from patient charts and the institution's total joint replacement registry. A multivariable logistic regression model was created to identify potential risk factors for neuropathy following THA while adjusting for potential confounders. We found that, of 39,056 primary THA cases, there were 81 cases of sciatic nerve palsy, giving an incidence of 0.21%. The factors with the greatest odds ratios for nerve palsy were: history of smoking (OR=3.45); history of spinal stenosis (OR=4.45), and time of day of 1PM or later (OR=3.98). We did not find limb lengthening, dysplasia, or type of fixation to be associated with nerve palsy. In conclusion, post-surgical neuropathy has a low incidence after primary THA, but at our institution, was associated with several factors. Spine-related comorbidities, such as spinal stenosis and lumbar spine disease, and smoking history should be closely monitored to inform the patient and surgeon for the potential increased risk of postoperative neuropathy following THA

Sequelae of Legg-Calve -Perthes disease (LCPD) and treatment of developmental dysplasia of the hip (DDH) can present a coxa breva or coxa magna deformity, sometimes associated with coxa vara. This unique deformity decreases the efficiency of the abductor mechanism, causing a Trendelenburg gait and hip pain, leg length discrepancy and leads to intra- and extra-articular impingement, and eventually osteoarthritis. Several surgical techniques have been advocated to treat this kind deformity, such as great trochanter transfer, relative femoral neck lengthening. We evaluated primary results of true femoral neck-lengthening osteotomy (TFNLO) in combination with periacetabular osteotomy (PAO) for treatment of Coxa Breva through surgical hip dislocation (SHD). Fourteen patients with Coxa Breva received true femoral neck lengthening osteotomy in combination of PAO through SHD between March 2020 and October 2023. Ten patients with minimum 1 year followed-up were retrospectively reviewed clinically and radiographically. Eight patients had Perthes disease, 2 had DDH received closed reduction and fixation during childhood. The mean age at surgery was 16 years (range, 12 to 31 years). Clinical findings, radiographic analyses including the change in horizontal femoral offset and the leg length discrepancy as well as complications were assessed. Horizontal femoral offset improved 19.5mm(6–28mm). Limb length increase 16.8mm(11–30mm). Mean HHS increased from 80.6(66–91) to 91.8(88–96). Complication: screw broken in 1(no need operation). Asymptomatic fibrous union of the great trochanter was found in 1. No infection and joint space narrow as well as nerve palsy happened. TFNLO combined with PAO can be effective for the treatment of patients with Coxa breva. But long term follow up is warranted

Thermal injury to the radial nerve caused by cement leakage is a rare complication after revision elbow arthroplasty. Several reports have described nerve palsy caused by cement leakage after hip arthroplasty. However, little information is available regarding whether radial nerve injury due to cement leakage after humeral stem revision will recover. In a recent study, radial nerve palsy occurred in 2 of 7 patients who had thermal injury from leaked cement during humeral component revisions. These patients did not regain function of the radial nerve after observation. We present a case of functional recovery from a radial nerve palsy caused by cement leakage after immediate nerve decompression in revision elbow arthroplasty[Fig. 1.2]

There is no consensus regarding the optimum frequency of ultrasound for monitoring the response to Pavlik harness (PH) treatment in developmental dysplasia of hip (DDH). The purpose of our study was to determine if a limited-frequency hip ultrasound (USS) assessment in children undergoing PH treatment for DDH had an adverse effect on treatment outcomes when compared to traditional comprehensive ultrasound monitoring. This study was a single-center non-inferiority randomized controlled trial. Children aged less than six months of age with dislocated, dislocatable and stable dysplastic hips undergoing a standardized treatment program with a PH were randomized, once stability had been achieved, to our current standard USS monitoring protocol (every clinic visit) or to a limited-frequency ultrasound protocol (USS only until hip stability and then end of treatment). Groups were compared based on alpha angle at the end of treatment, acetabular indices (AI) and IHDI grade on follow up radiographs at one-year post harness and complication rates. The premise was that if there were no differences in these outcomes, either protocol could be deemed safe and effective. One hundred patients were recruited to the study; after exclusions, 42 patients completed the standard protocol (SP) and 36 completed the limited protocol (LP). There was no significant difference between the mean age between both groups at follow up x-ray (SP: 17.8 months; LP: 16.6 months; p=0.26). There was no difference between the groups in mean alpha angle at the end of treatment (SP: 69°; LP: 68.1°: p=0.25). There was no significant difference in the mean right AI at follow up (SP: 23.1°; LP: 22.0°; p=0.26), nor on the left (SP:23.3°; LP 22.8°; p=0.59). All hips in both groups were IHDI grade 1 at follow up. The only complication was one femoral nerve palsy in the SP group. In addition, the LP group underwent a 60% reduction in USS use once stable. We found that once dysplastic or dislocated hips were reduced and stable on USS, a limited- frequency ultrasound protocol was not associated with an inferior complication or radiographic outcome profile compared to a standardized PH treatment pathway. Our study supports reducing the frequency of ultrasound assessment during PH treatment of hip dysplasia. Minimizing the need for expensive, time-consuming and in-person health care interventions is critical to reducing health care costs, improving patient experience and assists the move to remote care. Removing the need for USS assessment at every PH check will expand care to centers where USS is not routinely available and will facilitate the establishment of virtual care clinics where clinical examination may be performed remotely

Objective: The primary aim was to describe the epidemiology of the Holstein-Lewis humeral shaft fracture, its association with radial nerve palsy and the outcome regarding recovery from the radial nerve palsy and fracture healing. The secondary aim was to analyze the long-term functional outcome. Setting: Six major hospitals in Stockholm County. Design: Descriptive study. Retrospective assessment of radial nerve recovery and fracture healing. Prospective assessment of functional outcome. Patients: All 27 patients with a 12A1.3 humeral shaft fracture according to the OTA classification satisfying the criteria of a Holstein-Lewis fracture in a population of 358 consecutive patients with 361 traumatic humeral shaft fractures. Intervention: Nonoperative or operative treatment according to the decision of the attending orthopedic surgeon. Main Outcome Measurements: Recovery of the radial nerve, fracture healing and functional outcome according to the Short Musculoskeletal Function Assessment (SMFA). Results: The Holstein-Lewis humeral shaft fracture constituted 7.5% of all humeral shaft fractures and was associated with an increased risk of acute radial nerve palsy compared to other types of humeral shaft fractures, 22% versus 8% (p< 0.05). The fractures of six of the seven operatively treated patients healed after the primary surgical procedure while one fracture healed after revision surgery. The fractures of all patients treated nonoperatively healed without any further intervention. All six radial nerve palsies (two patients treated nonoperatively and four operatively) recovered. The functional outcome according to the SMFA was good with no differences between the nonoperatively and operatively treated patients: SMFA dysfunction index 7.6 and 9.7, respectively, and SMFA bother index 6.1 and 6.8, respectively. Conclusion: The Holstein-Lewis humeral shaft fracture was associated with a significantly increased risk of acute radial nerve palsy. The overall outcome regarding fracture healing, radial nerve recovery, and function is excellent regardless of the primary treatment modality, i.e. operative or nonoperative treatment. The indication for primary operative intervention in this fracture type appears to be relative

Introduction. Treatment for distal third shaft fractures of humerus is very challenging. They are commonly treated with plating. Plating has complications of iatrogenic radial nerve palsy. We report our case series of distal third fractures of humerus treated with retrograde Halder Humeral Nail. Materials/Methods. Since 1994 to 2010 we have 576 fractures of humerus treated with retrograde Halder Humeral nail. Of these 45 fractures were distal third of humerus. Average age of patients at the time of surgery was 30.4 years (Range 15–82 years, Median 33 years). Of 45 patients 26 were females and 19 males. Three out of 45 had non union at the time of presentation. All patients were followed until clinical and radiological signs of union. One patient was lost to follow-up. Results. Average time to fracture healing was 13.9 weeks (Range 9–36 weeks). There were two cases of non union, one healed at 9 months with 2. nd. surgery. There was one reported case of infection. Seven patients had nail removal electively. All the patients achieved full range of elbow and shoulder movement. No reported cases of iatrogenic radial nerve palsy. Conclusion. Our results of distal third fractures of humerus treated with retrograde Halder Humeral Nail are excellent. It avoids big exposure as needed in plating and complication of iatrogenic radial nerve palsy

Introduction. Correction of multiplanar bone deformities in children is indicated for prevention of secondary orthopaedic complications. Different problems related to surgical intervention were reported: non-union, delayed union, recurrent deformity, refracture, nerve palsy and pin tract infection. The aim of this study was to show the results of children femur and tibia bowing deformities by Ilizarov technique. Materials and Methods. We analysed 27 cases of children femur and tibia bowing deformities under the age of 13 yrs. Simultaneous deformity correction in femur and tibia was done with Ilizarov device in ipsilateral side. Contralateral side was operated after 14 days. Results. The duration of Ilizarov fixation was 130 days on an average. The deformity correction was achieved with a proper alignment in all the cases. Conclusions. Bowing of femur and tibia can be corrected simultaneously by Ilizarov fixation with minimum complications. There were no recurrent deformities in our cases

Aim. Treatment for distal third shaft fractures of humerus is very challenging especially if its comminuted and bone is osteopenic. They are commonly treated with plating. Plating has complications of iatrogenic radial nerve palsy. We report our case series of distal third fractures of humerus treated with retrograde Halder Humeral Nail. Materials and methods. Since 1994 to 2010 we have 576 fractures of humerus treated with retrograde Halder Humeral nail. Of these 45 were distal third extra articular fractures of humerus. Average age of patients at the time of surgery was 30.4 years (Range 15–82 years, Median 33 years). Of 45 patients 26 were females and 19 males.3 out of 45 had non union at the time of presentation. The nail was locked distally with one or two screws and proximally with a screw and tripwire. The entry point of the nail was roof of olecranon fossa (contrary to standard retrograde nails where it is an inch above olecranon fossa) This design of nail allows it be used for even very distal fractures. All patients were followed till clinical and radiological signs of union. 1 patient was lost to follow up. Results. Average time to fracture healing was 13.9 weeks (Range 9–36 weeks). There were 2 cases of non union, one healed at 9 months with 2. nd. surgery. The other non union was asymptomatic and did not agree for further surgery. There was one reported case of infection.7 patients had nail removal electively on request. All the patients achieved full range of elbow and shoulder movement. No reported cases of iatrogenic radial nerve palsy. Conclusion. Our results of distal third fractures of humerus treated with retrograde Halder Humeral Nail are excellent. It avoids big exposure as needed in plating and complication of iatrogenic radial nerve palsy

Aim. The current literature indicates that hip arthroscopy is safe in both adolescents and adults with good early outcomes but there are no available studies that directly compare the outcomes of this procedure for mixed indications between these two groups. Method. This was a prospective cohort study of 102 consecutive supine hip arthroscopies in 96 patients (48 adolescent (<18) hips, mean age 13.9 years and 54 adult (>18 hips), mean age 33.8 years) at a tertiary referral paediatric and adult university hospital followed-up for a minimum of two years. Patient demographics, indications for surgery, Modified Harris Hip (MHHS) and Non-Arthritic Hip (NAHS) scores, operative interventions and complications were recorded. Results. At two-year follow-up, the MHHS improved from a mean of 55.3 to 87.5 (p<0.05) in the adolescent group and from 58.7 to 86.9 (p<0.05) in the adult group while the NAHS improved from 57.1 to 86.7 (p<0.05) in the adolescent group and from 61.4 to 87.4 (p<0.05) in the adult group. There was no statistical significance difference in outcome between the two groups at 2 years. With respect to complications, there were 2 cases of transient lateral femoral cutaneous nerve palsy (1 adolescent and 1 adult) that resolved spontaneously. There were 3 transient pudendal nerve palsies that resolved spontaneously in the adolescent group by 4 weeks. There was no difference in mean operative traction time in both groups (47.6 minutes in adolescents versus 48.3 minutes in adults; p<0.05). No cases of proximal femoral physeal growth disturbance or osteonecrosis were seen at final follow-up. Conclusion. This study confirms that hip arthroscopy for mixed indications leads to good early outcomes with low complication rates in adolescent and adult patients. The incidence of pudendal nerve palsy in the adolescent group is however noted and is of concern
